J-3 - So many memories. In the late '70s, I soloed in a J-3 Cub at the Searcy, Arkansas airport. It was Sunday early afternoon so no one was around to tear off my shirt. Like many things, the first is always special so I've always had a particular fondness for the Cub. Mr Taylor did a great job designing it. Thanks, Jimmy.
My first plane ride was in a J3 in 1957 (age 7) over Norfolk, Va. At that time, flying over the Navy bases was ok and the pilot took us to see the aircraft carriers and other ships. I joined the Navy in 1969 and was stationed at Norfolk from 70 to 73.
You can take the valve out of the guide you know. Just reach up through the bottom spark plug hole with mechanical fingers and grab the stem. Then you can ream a valve guide that is leaded up. You look up through the exhaust port to line it up again to reinstall it. Stick a tiny inspection light down through the top spark plug hole so you can see better inside the cylinder. Also, I recommend you put a GoPro on a stick and slide it up through the wing inspection holes so you can check to see how many rib stitch cords the mice ate. The next to last plane I worked on before I retired was a J-3. The owner begged me three times before I told him to bring it in. I figured how bad could someone screw up a simple plane like that. Boy, did i find out. 30 plus write ups and an AD note that was never done since the early 80s. Also I have a Cub story for you from way back. When Piper started hanging Lycomings on them, they were operating with zero extra capital. One time a customer came in to pick up his new Cub and they still didn't hadn't bought the engine for it yet. As soon as the customer handed them the check, they rushed it to the bank and sent a man to Lycoming, which was just 20 some miles down the road form Lock Haven, to pick up the new engine. To kill time, Mr. Piper gave the man an extended tour of the manufacturing plant while they got to finishing up the plane and taking a test flight in it. Also, Mr. Piper had Lycoming agree to build the pallets they shipped the engines on with a special type of plywood top, which became the floor boards in the plane. That is one reason they were under $1000 new.
Fixed a stuck valve on the ramp in my Luscombe back in college using a mechanical finger (tool retrieval tool). Had to remove the valve and ream the guide. Worked great. From start to finish it took all of 45min to an hour and I was outta there! My roommate looked at me like “you’re gonna hop in that and fly home now?” Sure did!
You can actually do it without the mechanical fingers in the exhaust port so you can leave the exhaust in place. Just bend up a couple hook tools from stiff wire and manipulate thru the plug holes. Helps a lot to have a nice strong magnet on a stick that fits in the guide. Good stuff!
I know nothing about aircraft engines but a fair bit about flat four VW's. Remove pushrod from tappet. Move tappet. Spin valve enthusiastically. On VW's I use a small battery hammer drill. DON'T use lapping compound :)
I was born in Lock Haven PA where that puppy was built! If you’re ever in the area, there’s a nice Piper museum in the old factory! It’s worth the visit! Great Job Jimmy! Hope to see her fly!
You do NOT have to take the engine apart if the valve falls in. In fact, knocking it into the cylinder is part of the process you can do to clean the valve stem and ream the guide without pulling the cylinder. You can route a set of mechanical fingers in the valve guide, grab the valve, and put it throught the spark plug hole, then rotate the prop until the piston holds the valve while you clean it. Let the valve back down when you're done, then use the mechanical fingers through the spark plug hole to put it back into the guide and lap it. Had an A&P do this to 2 cylinders on my 150 when I got a stuck valve 10 miles from an airport in 2019.
Great video! Jessie is an awesome addition. seems like a smart lad and knows his stuff. How you managed to score Morgan freemans voiceover at the end is beyond me. Ha Ha

A 25/32 nds wrench is one 32 nd over 3/4. When do you need to be that precise?? To get the mud dobbers out, put the shop vac hose in one access port and reach in through another to break it up. Otherwise you'll have dirt all inside the wing.
Glad to see you have the issues with the engine worked out. This looks to be in really good shape. You can do some aerobatics in these planes. Matter of fact, a nationally known stunt pilot, Gene Griffith, currently holds the world tail spin record in a Piper J-3 Cub where he performed 87 consecutive turns from a height of 12,000 feet in the J-3 in which this record was set in back 1950 in Zanesvile, Ohio and has never been broken. It was a very windy day when Gene set this record. Many pilots have attempted to break his record in the J-3 but all have failed.
Jimmy? I think you did the leak down wrong on the cylinders that had leakage. I saw the prop in the same position for both cylinders on each side and the prop should be 180 degrees for each cylinder for a total of 720 to cover all 4 cylinders on a 4 stroke engine.. You have to check for compression stroke on each cylinder separately. If one is TDC, the other one behind it is not TDC. Maybe you did rotate the prop but I did not see that for the other two cylinders. Just thought it weird that two cylinders had leakage and two did not.
I have used Marvin Mistry Oil on my car knocking engine and it worked like magic. I did smoked the neighborhood for about 15m but ever since then I am a strong believer in the product.
Marvel Mystery oil works wonders for old J-3 engines. Also, Aero Kroil is your friend for things that are stuck. Mouse Milk should be in your kit next to the WD-40…just saying. 😊
You know the joke about MMO, right? The mystery is - what's it good for? I used to buy a lot of that when I owned a C-85 in a Cessna 140. Until I started to add TCP to the fuel.
Perfect plane to put a Yamaha Apex motor in it. Just spinning the valve with a drill can clear carbon off the seat. You might not even need valve grind compound. Spray some top engine cleaner in spark plug hole. Done it many times.
I've done it, and it has worked at times. About stuck rings, I've had luck filling the cylinder with two-stroke oil, and letting it sit for a week or so, change the engine oil, and run it up to working temperature.
For stuck rings, valves, dry carbon in engines which have not run for a while. I filled the cylinders with diesel for a few days. The diesel will go in the motor oil, no damage you need to change the oil anyway. Diesel has a greater means of going into places and leaking more than other fluids.
for carbon removal soak the rings and valves with pb blaster then run the engine get it hot and spray water into the carb while its running--the water will crystalize the carbon and make it break up
You missed the one thing that made the Cub a basic aircraft, the piece of wire protruding out of the gas cap in front of the windscreen to let you know if you had gas left or to start looking for a field. If it was bouncing up and down you were good to go. In 1962 my dad bought a 47 cub for 1200 dollars in flying condition. Best thing about a fabric aircraft is you need to work on something internal cut the fabric off fix it and in a weeks time have it back good as new fairly cheap. (if you do the recovery process yourself). You will love flying around with the door down . If the locals weren't so eager to turn in every little infringement another fun thing was to toss out a roll of toilet paper and see how many times you could cut it with your wing before it got too low.
That lil cub slices n dices...is what yer tryin to say,eh Jimmy?Never knew you were a musician too Jimmy!Piper Cub=is the go cart of flyin machines!The only thing that is more minimal for powered flight would be Para-gliding...
I had a stuck valve on the #3 as well recently. The rope trick wouldnt work, so I just popped that bad boy off, got the valve out, cleaned it and the intake valve up, used a nylon brush to clean the guides, and gave it a good hone before I put it back on. Helps if you have the real gasket push rod tube conversion. That was the first change I made to my engine.
always hammer knock the valve/s multiple times after putting the keepers back in, regardless of being new or used and knock them more if used(carbon does bad things!). I'll follow that with saying, always stand well off to the side in case all hell breaks loose! I have retrieved parts from across the garage a few times over the years, but never had a valve get eaten afterwards(yet)
Jimmy, ask you A&P or the AI this question. I was told by my instructor when I first started lessons was to never pull the prop thru that the Mag's trip.The reason was if you have a bad ground the engine could possibly fire over when the mag makes contact.
keep air hooked up while you tap on the valves with the hammer. The air pressure will blow the chunk out at the moment hit it. Do this all the time on automotive stuff, and we do use leak down testers in the automotive world. and while I was typing you got to that air pressure part...lol.
That's pretty cool that you mentioned Dewey. His private strip is about 20 minutes away from my house. I had the honor of finally meeting him and flying in his New Standard bi plane last year. He is a great guy that shares the passion of aviation with others. I totally agree with you on Jimmy reaching out to him even for a video.
Very educational, and the absolute simplicity of the J-3 blows me away...now I'm 100% certain I will NEVER climb into anything smaller than an Embraer 145.
@Max Nafe Horsemanship Most people learn to fly in airplanes with tricycle landing gear. If you take flying lessons in a tailwheel airplane, or what the FAA refers to as "conventional landing gear" there is no requirement to have a tailwheel endorsement, and you never need to get a tricycle gear endorsement, because that is the less difficult of the two types. Just the standard required check ride in the aircraft type is all that is needed.
Also known as the Italian tuneup. Old schoolers on automotive engines would pour water down the carburetor while giving it the beans…. Cheap steam clean, plus worked to reseat stuck piston rings
Man this plane brings back memories... my first flight in a small craft was this very model... pretty cool to learn some more history about it... thanks Jimmy 😎👍
I'm not sure where you got your history lesson but I got mine from my grandfather who was a Great Lakes dealer and pilot in the 30's. My grandfather preferred the Champ over the Cub and said one of the benefits was it could be soloed from the front seat. He said the reason you couldn't solo a Cub from the front seat was due to lack of spin recovery in certain instances. I don't remember the details for pilot weight and the manoeuver that got you into an unrecoverable stall but they cracked a few planes up before the rear seat solo mandate was put in place. Maybe an inverted flat spin? And 90% trained in a Cub? Not sure where you got that number either. The Stearman biplane was a trainer as was the PT-19 monoplane. Several other airplanes were also used as trainers.
Dynamic Carbon Removal: Setup a small hose with shutoff from a water bottle to a vacuum source on cylinder to be cleaned. Start engine, set RPMs to operating speed, open valve to water, don't let enough in to slow engine. Watch the smoke out of exhaust! This tip cam from Dealer Tech @ American Honda, for a grannied Gold Wing that ran like crap due to carboned valves not allowing vacuum throttle pistons to operate properly. Worked perfectly, smelled terrible while carbon was expelled.
That is not a 46 if it has a wood wing spar. Also, I have never seen a curb that does not have a steerable tail wheel. It steers by the tailwheel, connected through springs, to the rudder.
love to watch people with the knowledge go to work....years ago I got a ride over big peach fields in S.C. in a J3, some of those boys didn't have licenses and a J3 was cheap...
I don't even have a pilots license, but I heard the name of the Piper Cub a LOT and never anything bad. Hope this thing works for you. If I recall correctly, this is the one you want your kid to start on. I've done that kind of valve work on a few cars but I would never risk doing it on an assembled engine. Way too much could go wrong. No more time and only a few bucks for a head gasket to pull the head and do it safely.
You need Tarryl from Tarryl Fixes All to fix your sticky valve. It would be a UA-cam sensation. By the way Marvel Mystery Oil or transmission fluid added to your oil and fuel will prevent any carbon problems in that engine.
YES YES YES Taryl could show Jimmy a crap load of tips and tricks to save time and work when it comes to mechanical innovations,Taryl is "The Man" !!!!!!!!!!!! Wish we could get those two together maybe even get a skit too !!!!!!! They call me "Handy Andy" ,!!!!!!
Carbon problem in a gasoline engine. Maybe your horse needs a drink of water. Start the engine, warm it up, hold throttle a little above idle, pour a small amount (1/2 ounce maybe) of water into the intake. The water will fracture the hot carbon and it blows out the exhaust.
I have never heard about using water, but I have used Marvin Mistry Oil on my car knocking engine and it worked like magic. I did smoked the neighborhood for about 15m but ever since then I am a strong believer in the product.
We had a 1956 Cessna 172 with an O 300 Continental in it that used to occasionally get sticky valves. The trick we used was to add Marvel Mystery Oil to the fuel tanks and then run the crap out of the engine like you did that usually did the trick. Once we started using Marvel Mystery Oil regularly, we never had a problem with stuck valves again
I remember as a 10-12 year old kid in the early to mid 70s, going through the Piper plant tour with my neighbors. I dont remember much, but what I do, it was pretty cool. It's long gone now.
Ive got 1941 J3. At least some parts from 41. The 85 Cont makes it go zoom zoom. Flying with the door and window hinged up under the wing is marrrvelousss.
I worked in a small car engine rebuilding shop in the 70's. Most of it was carry out work but they had a bay for R&R work too. They rebuilt a Cadilac engine in a car that had some sort of front wheel drive that made it a very tough job. They thought it would be a good idea to put chrome rings in it but they couldn't get them to seat. In desperation the owner poured Bonami (pumice) in each spark plug hole & ran it. It worked to seat the rings then wear them out all in about 5 minutes so the engine came out again. Somehow, I flashed back to this memory.
Several decades ago I met a gentleman who had bought a piper J2 cub all "original" he was extremely happy about the plane but he was confused about how low the flight time was. I mention to him that it was a nice winter airplane to which I received a puzzled look. A couple months later the temperature hit 95 degrees and he found out why I said it was a nice winter airplane . Anyone care to comment? Jimmy you still haven't handproped , do something with 235 hp. Or more. Now you have handproped . No conventional gear rating, what have you been doing? Go get it and get a glider rating while you're at it . Your options open up dramatically. When I added those ratings to my ticket my insurance cost went way down .
I flew a Cub from sea to shining sea with a pal I co-owned it with .. From east to west, IFRR (I follow Rail Roads), north through new England, west to Minnesota, into Canada, across the plains, through and not at all over the Rockies (didnt go that high) landing in Vancouver. The trip took just over a week, two 20 somethings on an trip funded with hamburger flipping money ...Sleeping under the wing or on a hangar floor if we were lucky, sometimes taken home for a good dinner and sometimes a warm coke and stale airport peanuts. A great and memorable adventure for two young men - one that I think might be very hard if not impossible to repeat now. My J3 was a good airplane, it taught me a lot more than just how to fly.
She reminds me of my landlord & roommate who is also a A&P inspector along with being a pilot & owner of a fixed wing and rotor aircraft (yes she’s a over achieving woman!) but she is really good at what she does!
Old school trick we used to do is throw transmission fluid down in the jugs. There's a lot of detergent in there and it has a tendency of breaking free a lot of carbon. It's how I used to free up rings on the engine that's been sitting for a year or two as well it lubricates. It will billow a lot of smoke till it burns off
My dad had one that was used during WWII. I was almost born in it. Seriously! I grew up around the J-3 Cub. I started flying lessons really early but official lessons at age 11. My dad had red and green bicycle lights powered by D-cell batteries. He had to change them about every 3rd or 4rth flight. I would love to have a cub these days. I have an Ercoupe which my dad said to never buy. He was afraid I would be limited to 2 axis flight. Mine has rudder pedals. We have a no start inside the T-Hangar rule at Edgefield Co. SC, because it blows dust all over the other planes in the hangar.
My Uncle Hubert had a '46 J-3 Cub, he propped it with one hand, my Navy pilot dad used both, the stand in front positioned to fall backwards if you lost your balance. Hubert bought it after the Piper salesman who lived in Kansas flew him in his, and showed him how he took off using a post with a cable and a hook in the wing, due to his EXTREMELY short runway, the plane would circle the post 2× and as it came around to his runway, he pulled a lever that opened the hook and then had sufficient ground speed for takeoff. Hubert used the GenAv airport in Oklahoma City, HIS back yard was WAY too small.😁 👍🇺🇸😂
Amazing video Jimmy. It is quite clear you have a love of airplanes. There has to be only a select few people who know this much detail about these old vintage machines. Fascinating stuff. Thanks for sharing.
You need a training to start up the Engine. Check the Prop...magnetos...timing make shure the vaporizer is clean, change to new fuel. We always pulled 3 times back and than try to start. If everything is just like it has to be....it will start with the first try. So get the ass up in the air. It was in the early 80 when i worked on it. Your mecanik ....? Is it Jane Reisiger?
Oooh.. yeah Jimmy going to get training on tail dragger I guess! Awesome, that's a pretty important cert to get I'm guessing!! sweet another set of videos!
I always do the compression test in the bottom plug hole. Been bitten too many times with carbon falling into the valve seat and making the valve leak.
The main spars (fore and aft, there are two), support the wing (singular). the model J3 is not a bi-wing aircraft and therefore does not have wings. This is evident by referencing Note 1 in the aircraft TCDS, number: ATC 660
I helped rebuild 22 of those Piper Cubs. Don't forget to check the welds in the rear of the fuselage. Everything I worked on had metal spars. I think they cost $500 Army surplus.
Safety spoiler: Stay clear of the prop arc when conducting a cylinder pressure test. 70PSI can kick the prop over and the prop can then knock you out or worse. Not to mention that mud daubers love to weigh down fabric aircraft with their nests. 🤠
Jimmy, that engine is 64 horse power not BTU or British Thermal Unit. Power is a unit of energy over time while BTU is just energy. All the BTUs are in the gas. AVGAS has 364 BTUs per pound mass so if this j3 has 12 gallons of gas, multiply by 6 lbs/gal you get 72 lbs so your j3 cub would have 26,208 BTUs if filled with gas, not 64.
And... the compass was an optional accessory! Dad owned a flight service in Iowa. Mom would hand prop the Aronca Chief, fly out to her mom & dad's farm, land on the dirt road and taxi in the driveway to have afternoon tea with her mom. Then hand prop it and fly home!
In the late thirties the US government asked Piper to develop a low cost aircraft that colleges could buy (with, I think, government subsidy) very cheaply and offer students flight training. With what was happening in Europe the military wanted to have a pool of people who already knew the basics of flight. I flew a J3 a couple of times, it's the purest form flight.

40:19 Keepers ! That's one thing to know, when you rebuild small engines as a hobby. How do you clean the compound, after lapping ?
An hour of video of Jimmy working on airplanes, Priceless!
Absolutely ☆☆☆☆☆☆☆☆☆☆
For stuck rings, valves, dry carbon in engines which have not run for a while. I filled the cylinders with diesel for a few days. The diesel will go in the motor oil, no damage you need to change the oil anyway. Diesel has a greater means of going into places and leaking more than other fluids.
Exactly what I learned to fly in, the J3 cub at Northeast Regional Airport many many years ago, back when it was Aerosport owned by the Mosers.
for carbon removal soak the rings and valves with pb blaster then run the engine get it hot and spray water into the carb while its running--the water will crystalize the carbon and make it break up
Fire it up!
😉👍 I've used that same valve lapping method on my lawn mower... 😬 Hopefully that prop doesn't want to cut the grass too...
I watch the first video. I think you’re getting an awesome deal. I hope you’ve done it already.
PS, I think the cub is a 1940.
You missed the one thing that made the Cub a basic aircraft, the piece of wire protruding out of the gas cap in front of the windscreen to let you know if you had gas left or to start looking for a field. If it was bouncing up and down you were good to go. In 1962 my dad bought a 47 cub for 1200 dollars in flying condition. Best thing about a fabric aircraft is you need to work on something internal cut the fabric off fix it and in a weeks time have it back good as new fairly cheap. (if you do the recovery process yourself). You will love flying around with the door down . If the locals weren't so eager to turn in every little infringement another fun thing was to toss out a roll of toilet paper and see how many times you could cut it with your wing before it got too low.
I cut that wire off on my J3... so it wouldn't scare me.
This series is going to be epic.
You are sooooo right!!
That lil cub slices n dices...is what yer tryin to say,eh Jimmy?Never knew you were a musician too Jimmy!Piper Cub=is the go cart of flyin machines!The only thing that is more minimal for powered flight would be Para-gliding...
Love these longer vids, espescialy this type content, please do the other aircraft as well, thank you again for your great contributions to aviation
I'd love to see the others as well. I love anything old, and planes age well.
I'm 77 yrs old and I'm still firing on all cylinders. That is a nice airplane. Watching you from the beginning from Tampa.
Love your videos man. Makes me want to learn to fly!!!
Tail dragger takes 20 hours to get a license to fly. Like the cub.
I'm told.
Go get some seat time. Get an ultralight and be flying for less than a good used 10 yr old car.
between this guy and Mike Patey that's why I'm getting my License
I had a stuck valve on the #3 as well recently. The rope trick wouldnt work, so I just popped that bad boy off, got the valve out, cleaned it and the intake valve up, used a nylon brush to clean the guides, and gave it a good hone before I put it back on. Helps if you have the real gasket push rod tube conversion. That was the first change I made to my engine.
I love the Morgan Freeman impression. Whoever did it is really good.
always hammer knock the valve/s multiple times after putting the keepers back in, regardless of being new or used and knock them more if used(carbon does bad things!).
I'll follow that with saying, always stand well off to the side in case all hell breaks loose! I have retrieved parts from across the garage a few times over the years, but never had a valve get eaten afterwards(yet)
One of my first flights was in a J-3 Piper Cub back in the early 1970’s. I felt safe and privileged to have done so. Great airplane!
Jimmy, ask you A&P or the AI this question. I was told by my instructor when I first started lessons was to never pull the prop thru that the Mag's trip.The reason was if you have a bad ground the engine could possibly fire over when the mag makes contact.
Not only are the Piper cub series classic aircraft. They are the most cloned aircraft in history.
Awesome video Jimmy!! I fly and restore these old girls. This one is a 1940 J-3F. Originally came with a 65 hp Franklin engine. Great find. 😁👌🏼
Love you Jimmy! I love these types of episodes! Wish I could fly with you one day!
Loved the narration at the end
I was at Sun and fun today and guess who I ran into one of the nicest men that I follow ,made my whole vacation.
keep air hooked up while you tap on the valves with the hammer. The air pressure will blow the chunk out at the moment hit it. Do this all the time on automotive stuff, and we do use leak down testers in the automotive world. and while I was typing you got to that air pressure part...lol.
You need to get Dewey Davenport to train you in those taildraggers and maybe ferry some of them home for you.
I love watching his ferry flights.
That's pretty cool that you mentioned Dewey. His private strip is about 20 minutes away from my house. I had the honor of finally meeting him and flying in his New Standard bi plane last year. He is a great guy that shares the passion of aviation with others. I totally agree with you on Jimmy reaching out to him even for a video.
LOL.. I guess I am old. I still think of tail draggers as the norm and trikes as something new.
Jimmy is a real stand-out. The coolest American on the planet !
I have a hard time with how Jimmy holds himself…his demeanor per se.. I can see how he’s so popular on UA-cam….I wish him well and prosperity…🇺🇸
Watching from Zambia. Can't wait to see the outcome of the Elvis jet.
Very educational, and the absolute simplicity of the J-3 blows me away...now I'm 100% certain I will NEVER climb into anything smaller than an Embraer 145.
I see a tailwheel endorsement coming in Jimmy's future!
I may not know much. I didn't even know you needed a special license for them. My dad had a 48 Luscome taildragger. I thought anyone could fly them.
@Max Nafe Horsemanship
Most people learn to fly in airplanes with tricycle landing gear. If you take flying lessons in a tailwheel airplane, or what the FAA refers to as "conventional landing gear" there is no requirement to have a tailwheel endorsement, and you never need to get a tricycle gear endorsement, because that is the less difficult of the two types. Just the standard required check ride in the aircraft type is all that is needed.
Also known as the Italian tuneup. Old schoolers on automotive engines would pour water down the carburetor while giving it the beans…. Cheap steam clean, plus worked to reseat stuck piston rings
Watched somebody do that with Marvel Mystery Oil with his son's '77 Honda CVCC: smoked-out half the airport for an hour!
My dad used ATF, just a drizzle into the carb at high idol, an killed mosquitoes all around. But it also blew out cylinder crud.
Yep still that’s the old school approach for sure! Just a drizzle… lol
Man this plane brings back memories... my first flight in a small craft was this very model... pretty cool to learn some more history about it... thanks Jimmy 😎👍
I'm not sure where you got your history lesson but I got mine from my grandfather who was a Great Lakes dealer and pilot in the 30's.
My grandfather preferred the Champ over the Cub and said one of the benefits was it could be soloed from the front seat.
He said the reason you couldn't solo a Cub from the front seat was due to lack of spin recovery in certain instances.
I don't remember the details for pilot weight and the manoeuver that got you into an unrecoverable stall but they cracked a few planes up before the rear seat solo mandate was put in place.
Maybe an inverted flat spin?
And 90% trained in a Cub? Not sure where you got that number either. The Stearman biplane was a trainer as was the PT-19 monoplane. Several other airplanes were also used as trainers.
How many times will this 'FREE AIRPLANE if I can start it' trope going to be used for clicks? Stop it. It's cringe.
This is because of the success rebuild rescue had with the 401 he got for free the same way.
It's ok if it's true as long as you realise it won't fly for free.
Ya did it!
If its true , its okay.
"I bought these free aiplanes for $100,000 and i get to keep them if i fix them. even though i bought them"🤣
Dynamic Carbon Removal: Setup a small hose with shutoff from a water bottle to a vacuum source on cylinder to be cleaned. Start engine, set RPMs to operating speed, open valve to water, don't let enough in to slow engine. Watch the smoke out of exhaust! This tip cam from Dealer Tech @ American Honda, for a grannied Gold Wing that ran like crap due to carboned valves not allowing vacuum throttle pistons to operate properly. Worked perfectly, smelled terrible while carbon was expelled.
Hey Jimmy I have about 20 of the 25/32 wrenches in all the flavors where can I send some to you at
Jimmy the 12 point nuts that held the brakes on the main wheels of a Boeing 727-227 are 25/32". Still have that socket in my tool box.
Love the borescope. Mike Busch student. Would have liked to have seen the cylinder wall.
That is not a 46 if it has a wood wing spar. Also, I have never seen a curb that does not have a steerable tail wheel. It steers by the tailwheel, connected through springs, to the rudder.
love to watch people with the knowledge go to work....years ago I got a ride over big peach fields in S.C. in a J3, some of those boys didn't have licenses and a J3 was cheap...
I don't even have a pilots license, but I heard the name of the Piper Cub a LOT and never anything bad. Hope this thing works for you. If I recall correctly, this is the one you want your kid to start on. I've done that kind of valve work on a few cars but I would never risk doing it on an assembled engine. Way too much could go wrong. No more time and only a few bucks for a head gasket to pull the head and do it safely.
You need Tarryl from Tarryl Fixes All to fix your sticky valve. It would be a UA-cam sensation. By the way Marvel Mystery Oil or transmission fluid added to your oil and fuel will prevent any carbon problems in that engine.
YES YES YES Taryl could show Jimmy a crap load of tips and tricks to save time and work when it comes to mechanical innovations,Taryl is "The Man" !!!!!!!!!!!! Wish we could get those two together maybe even get a skit too !!!!!!! They call me "Handy Andy" ,!!!!!!
Carbon problem in a gasoline engine. Maybe your horse needs a drink of water. Start the engine, warm it up, hold throttle a little above idle, pour a small amount (1/2 ounce maybe) of water into the intake. The water will fracture the hot carbon and it blows out the exhaust.
I have never heard about using water, but I have used Marvin Mistry Oil on my car knocking engine and it worked like magic. I did smoked the neighborhood for about 15m but ever since then I am a strong believer in the product.
"I needs me one o them 25/32nd's wrenches" Classic. Good going Jesse...🤓
We had a 1956 Cessna 172 with an O 300 Continental in it that used to occasionally get sticky valves. The trick we used was to add Marvel Mystery Oil to the fuel tanks and then run the crap out of the engine like you did that usually did the trick. Once we started using Marvel Mystery Oil regularly, we never had a problem with stuck valves again
I remember as a 10-12 year old kid in the early to mid 70s, going through the Piper plant tour with my neighbors. I dont remember much, but what I do, it was pretty cool. It's long gone now.
Ive got 1941 J3. At least some parts from 41. The 85 Cont makes it go zoom zoom. Flying with the door and window hinged up under the wing is marrrvelousss.
You can spray ...with a spray bottle( old windex type) those mud dobber nest with water and they will disintegrate into loose dirt.
I worked in a small car engine rebuilding shop in the 70's. Most of it was carry out work but they had a bay for R&R work too. They rebuilt a Cadilac engine in a car that had some sort of front wheel drive that made it a very tough job. They thought it would be a good idea to put chrome rings in it but they couldn't get them to seat. In desperation the owner poured Bonami (pumice) in each spark plug hole & ran it. It worked to seat the rings then wear them out all in about 5 minutes so the engine came out again. Somehow, I flashed back to this memory.
Several decades ago I met a gentleman who had bought a piper J2 cub all "original" he was extremely happy about the plane but he was confused about how low the flight time was. I mention to him that it was a nice winter airplane to which I received a puzzled look.
A couple months later the temperature hit 95 degrees and he found out why I said it was a nice winter airplane . Anyone care to comment?
Jimmy you still haven't handproped , do something with 235 hp. Or more. Now you have handproped .
No conventional gear rating, what have you been doing? Go get it and get a glider rating while you're at it . Your options open up dramatically. When I added those ratings to my ticket my insurance cost went way down .
Air density is the bane of almost all low powered high drag airplanes. Enough said......
@@bbrut3332 we have found a pilot .😊
Jimmy needs to find an ol' Stearman! 🤠
Glad you got that sorted out out. That Cub needs to be flown to get the cobwebs off.
I flew a Cub from sea to shining sea with a pal I co-owned it with .. From east to west, IFRR (I follow Rail Roads), north through new England, west to Minnesota, into Canada, across the plains, through and not at all over the Rockies (didnt go that high) landing in Vancouver. The trip took just over a week, two 20 somethings on an trip funded with hamburger flipping money ...Sleeping under the wing or on a hangar floor if we were lucky, sometimes taken home for a good dinner and sometimes a warm coke and stale airport peanuts. A great and memorable adventure for two young men - one that I think might be very hard if not impossible to repeat now. My J3 was a good airplane, it taught me a lot more than just how to fly.
Dude the Morgan Freeman impersonation had me straight Rolling!!! Buaaahaha
29:35 that's what we call an "italian tuning" - rpm the sht out of the engine at full throttle. :D
Great vid Jimmy - love to see more of them :D
Very nice comparison between a Cub and a Model A Ford, owing both, I agree.
Nice! Glad to have some content other than the Elvis jet.
Sooooo right ♡♡♡
She reminds me of my landlord & roommate who is also a A&P inspector along with being a pilot & owner of a fixed wing and rotor aircraft (yes she’s a over achieving woman!) but she is really good at what she does!
Old school trick we used to do is throw transmission fluid down in the jugs. There's a lot of detergent in there and it has a tendency of breaking free a lot of carbon. It's how I used to free up rings on the engine that's been sitting for a year or two as well it lubricates. It will billow a lot of smoke till it burns off
Every time I think America is done I watch Jimmy's world and am reminded how great the people are !
My dad had one that was used during WWII. I was almost born in it. Seriously! I grew up around the J-3 Cub. I started flying lessons really early but official lessons at age 11. My dad had red and green bicycle lights powered by D-cell batteries. He had to change them about every 3rd or 4rth flight. I would love to have a cub these days. I have an Ercoupe which my dad said to never buy. He was afraid I would be limited to 2 axis flight. Mine has rudder pedals. We have a no start inside the T-Hangar rule at Edgefield Co. SC, because it blows dust all over the other planes in the hangar.
My Uncle Hubert had a '46 J-3 Cub, he propped it with one hand, my Navy pilot dad used both, the stand in front positioned to fall backwards if you lost your balance.
Hubert bought it after the Piper salesman who lived in Kansas flew him in his, and showed him how he took off using a post with a cable and a hook in the wing, due to his EXTREMELY short runway, the plane would circle the post 2× and as it came around to his runway, he pulled a lever that opened the hook and then had sufficient ground speed for takeoff.
Hubert used the GenAv airport in Oklahoma City, HIS back yard was WAY too small.😁
👍🇺🇸😂
Amazing video Jimmy. It is quite clear you have a love of airplanes. There has to be only a select few people who know this much detail about these old vintage machines. Fascinating stuff. Thanks for sharing.
You need a training to start up the Engine.
Check the Prop...magnetos...timing
make shure the vaporizer is clean, change to new fuel.
We always pulled 3 times back and than try to start.
If everything is just like it has to be....it will start with the first try.
So get the ass up in the air.
It was in the early 80 when i worked on it.
Your mecanik ....? Is it Jane Reisiger?
Oooh.. yeah Jimmy going to get training on tail dragger I guess! Awesome, that's a pretty important cert to get I'm guessing!! sweet another set of videos!
I always do the compression test in the bottom plug hole. Been bitten too many times with carbon falling into the valve seat and making the valve leak.
The main spars
(fore and aft, there are two), support the wing (singular). the model J3 is not a bi-wing aircraft and therefore does not have wings.
This is evident by referencing Note 1 in the aircraft TCDS,
number: ATC 660
I helped rebuild 22 of those Piper Cubs. Don't forget to check the welds in the rear of the fuselage. Everything I worked on had metal spars. I think they cost $500 Army surplus.
My Dad had a Piper Cub in High School in Fargo, ND, in the late 50s. The stories are wonderful.
Safety spoiler: Stay clear of the prop arc when conducting a cylinder pressure test. 70PSI can
kick the prop over and the prop can then knock you out or worse. Not to mention that mud daubers love to weigh down fabric aircraft with their nests. 🤠
Pipercub J3 is always my favorite !!
Jimmy, that engine is 64 horse power not BTU or British Thermal Unit. Power is a unit of energy over time while BTU is just energy. All the BTUs are in the gas. AVGAS has 364 BTUs per pound mass so if this j3 has 12 gallons of gas, multiply by 6 lbs/gal you get 72 lbs so your j3 cub would have 26,208 BTUs if filled with gas, not 64.
And... the compass was an optional accessory! Dad owned a flight service in Iowa. Mom would hand prop the Aronca Chief, fly out to her mom & dad's farm, land on the dirt road and taxi in the driveway to have afternoon tea with her mom. Then hand prop it and fly home!
In the late thirties the US government asked Piper to develop a low cost aircraft that colleges could buy (with, I think, government subsidy) very cheaply and offer students flight training. With what was happening in Europe the military wanted to have a pool of people who already knew the basics of flight. I flew a J3 a couple of times, it's the purest form flight.
