Obvious there are some old school B&S enthusiasts in the room. Great info. Wheel falling off, starter and rope problems, smokey running, brings back memories of my old Snapper Comet 26 lawnmower. Although my engine was a 8hp vertical. So worn out I had to use starting fluid to get it to start. Had to stop at half a tank of gas to fill with oil again. About once a year the starter clutch would hang up and make the most embarrassing squeal imaginable.
the lifter area wasn't broken, it is a weak area that is welded to keep it from breaking. it is a common practice on briggs 5 hp engines that are professionally built by engine builders. That was a really good eyebrow shave job too! If you end up finding out that the engine still smokes, it could be the valve guides are worn out, or the piston is actually rocking in the bore, even with new rings.
Holy moly! I'm so glad to see one of these on your channel. In my hometown these are my go to, I build these engines on the regular for the dirt ovals my fellow hobbyists run on.
You have a briggs Raptor 3 engine. Can tell by the head having 3 tabs on it for the blower housing. I have a video from a couple years ago of our highly modified Flathead driving on my channel called "Limited Modified Briggs Flathead Go Kart"
@@moparlife4733 uh no sir i have 3 flatheads cranking around 25-40 hp and a 342 briggs cranking 35-40 hp and some clones with 13 hp a flathead with 12 hp and a (data expunged) cranking 110 hp
Glad to see all of the input from people that recognized this engine. I am truly hoping that you two can rebuild and save it so that it may live another day! Looking forward to the entire progress. Great find!!!!
I got an engine for 100 bucks and it was fully build and also had a Dyno cam in it and it had papers with it with all the cam numbers on it, cool little peice of history!
wow what a trip down memory lane. probably the first engine i worked on by my self and got running 20 plus years ago. the engine that got me into engines.
Holy cow you guys found somthing LOL that cam is a 107SS the 5's are S's the rpm range is 8500rpm 30ish LB of spring pressure 32-34 On ignition timing i can't remember the Lift the cam does but you should be able to find it Via Dyno cam's website or call them or email them and ask for the specs for the 107-SS cam it is a Very mild cam ran it in a few 5hp briggs Normally bore them out .15-30 over for this cam great thing about it was adding a billet Head some times you could get away with out haveing the relieving the head i know on the stock heads you did not have to but when i ran the 107-SS i ran Alky or E85 .
Also it might smoke depending on the oil you guys use i know mine smoked due to extra pressure in the crank case we ran 10w40 Royal Purple normally you would drill and tap the front of the crank case and add a catch can with a breather and redrain the catch can into the front oil drain just watch out for oil flowing into the carb at high RPM.
I would also like to note that rod is a Horstmann H Beam rod i have heard it being stronger than a ARC rod but i can't verify this but can tell you i have not seen one used in a good bit but alot of them where oversized and required the piston to be shaved a bit either way make sure you get the right rings proper oil and fuel and i promise this engine will be super fun shoot i might even dare say throw a mikuni flatslide and a billet head on it as well a billet flywheel.
After watching the video for the 4th time i really need to pay more attention to the videos the welding you seen above the lifter if i am correct it has brass inserts for the lifters and the welding that is done is more like a reinforcement because 5hp briggs where known for cracking right there under high rpm's with a large cam.
@@alfredo42o Well i can't say how they operate/work but i know every engine i get rather it be from ebay-Craigslist i never go by what the previous owner claims it has or had i always crack them open to see what is in them i have gotten lucky and scored a built 5hp from ebay for $50 guy claimed it was on a minibike but also said it was a stock engine he got from a friend in a trade so you win some and you loose some.
Hey just a quick tip, I think it may have already kinda been mentioned, but it’s a 99% chance that engine is set up for methanol fuel. The jets on the carb are drilled out much larger which is why you can’t get it to idle well. There should also be an offset flywheel timing key to advance the ignition to run on meth. Good luck with the build, love these old flathead monsters!
now this is the stuff we want to see. making something out of nothing from a box of Parts out of a barn. I just love that Isaac is still using the same old torque wrench that he's always had... you guys rock.
This is so awesome. I'm glad you're keeping it old school with the L-head. Giving it a performance engine...👌😍 It's a very good thing that it's driven via propeller shaft instead of a dang chain; proof that you guys care, you two are smart, and I'm grateful. Thanks for the vid!
The welded area on the block is done to reinforce the tapper bores. A bigger cam and stronger springs are known to blow the case out in that area. So glad to see the revival of the Rat Rod!
Permatex Aviation gasket maker!! Best shit for the side cover!! It's all I've ever put between the two halves of a Vw block!!(and many more places!) It's just good shit!! LOL
Built bunches of those. I used to think of you guys like 11 yo me, knocking around in the shed. reason i say is it took you guys awhile to figure out kill switches and relieable throttle return springs. now getting back to where i started like 25 years ago, really cool. say my buddys and i would use a steel flywheel key that looked half sheared to advance ignition timing for alcohol. also those old pulse jet carbs are a forgotten art but they can be rebushinged to get them tight again. so between the carb and tank you can use a peace of flat spring steel to raise the fuel level in the bowl. or build an intake adapter and use a motorcycle carb. lastly i think that engine was pretty healthy it just needs to warm up so everything can get tight. oh one more thing those alcohol engines run a light weight lubricant, can remember what we used but its similar to hydarolic oil.
The welds near the valve guides are there to strengthen the area. Flat head Briggs motors are known for cracking in that area. It was prepped as a race motor. You need to pull the valves, clean them, and lap them to the block. Clean up the carb and slap it back together. That motor will push close to 10 HP.
Love that your still keepin the briggs after waching this i decided to get my old brigs out wich is built but it sat for 2 years with water in it but suprisingly its still not seized so i think i should give her another chance.
I used to race those Briggs engines and they were something. Specially with the raptor kit. Makes me wanna pull the old blocks out and play a bit! Y'all are awesome keep it up! 👍
Love it you guys like tinkering with stuff. You're basically recording what you would be doing for fun anyhow. I really enjoyed what you were finding in that old motor that was fun
All hail the flathead thanks for another great video guys. Glad to see the rat rod wagon back. Good driving john way to not break anything. Yeah that was a crack at you Ike.
It was more likely a late 90s early 2000s stock appearing...the lifter bosses were weled for strength as they would usally break there due to higher lift..also its a dyno cam and they still produce cams...by the way im in south carolina have raced karts for 34 years lol...love the channel and hope y'all enjoy the old flathead
Great video ike and John! By the way, I fix small engines (mainly Briggs and tecumseh) and I recommend using a wire brush or a dremel with a wire wheel to clean the rust off the flywheel magnets and magneto. It should run a little better and start easier.
Get an impact driver, the kind you hammer from Harbor Freight. Cheap and my favorite hand tool. Working on old engines and motorcycles it never disappoints.
DUDE!!! I used to build those Briggs engines. The valve tappets get material added to them so they won't break when you put in a high lift cam! The lobe ramps up so fast, it will break the tappets right out of the block! That is probably a limited mod. cam, or an open class cam. They can turn 8-9000 rpm! I raced an open class cart back in the day. They'd run 70-90 mph depending on gearing! Awesome find! Check out the valve springs. The weight of the spring controls the rpm. If you plan to turn high rpm, get an aluminum flywheel!!!!! I saw one fly apart at the local track...a piece of hit a guy in the head and killed him! Nearly took his head off! No kidding...
I have seen several modified briggs flatheads with tig welded reinforcements near the lifter bores. In fact, if you go to DynoCams website and find their flathead cams, you'll notice almost every cam description recommends reinforcing in that area. On the Briggs Raptor III (not sure about the earlier ones) the block is much beefier and thicker in that area (between fins and crankcase it is noticibly reinforced from factory. I think the engine you have is actually a Raptor block
My pap used to race go-karts running alcohol, and it was very popular to rotate the cam, and even custom grind them (this was back in the mid to late 60s). It may be a home built custom grind cam.
10755 = 107.55 Horsepower on the dyno (at the crank, naturally). The Rat Rod Wagon would look even better if you could find a little spun aluminum fuel tank to put on top of the front axle!
That's like our old racing engines. Chain guard on the timing cover and it looked like our racing oil (Thor oils I believe). 5 hp Briggs made 13.6 hp. Bullet Racing Engines in Knoxville TN built them. I would also bet that is a Dyno Racing cam. Also, that carb could be jetted and worked to run methanol.
I have been watching for years this is the video that got me hooked. Today I finally subscribing. I challenge you to build another rat rode wagon. Then race them. Maybe do a 3 way build off. 3 rat rod wagons would be wild.
I’ve got a dyno cam in my old 5 horse Briggs that runs on methanol. Race my buddy’s on a 1/4 mile dirt track every Sunday and smoke the new predators that are supposedly 20+ hp. Also I’m a 6 foot tall 220 pound guy. These old motors are awesome. Carbs are easy to clean
One of these days I want to make a breather like that one, full over cam, over bore and stroked. Just gotta make sure I do it in a way that my family does not shit themselves when they figure out that I dismantled some power tool here at the farm to do it [HOP HOP HOP!]
@@isaacitllbefine7231 I don't have to say anybunny ENTICED me, I've dreamed of having cool go-karts since childhood! Now I'm OLD, and spent half a century working my ass off, I figure I should be allowed to have one. I have several 8hp blocks to choose from, all I/C [ball bearings on the cranks] and one is a Honda 8hp with OHC so the options are pretty open there. And if that fails me, I can always go out and find a used/junked 22hp-26hp V-twin some place for cheap and power build one of those up...
Ever thought that the jetting isn’t correct? So the AFR is off and causing it to smoke, also you should always try to hone it if you plan on the engine to seal up well the rings need to seat in good. And the welding you see is added support for the lifter galley when you have a more aggressive cam and valvetrain.
I love how the motor dances is on the table. Ever think about making a portable engine stand? Something you could clamp to the table. It's easier to tune when it's not dancing.
When I was racing go-carts if someone’s engine was smoking the track officials would stop you after you’re race and want to test your oil. Guys were opening the ring gaps up and putting an additive to their oil. Cant recall exactly what they called the stuff. So with the blow-by it would burn the oil and additive to make more power. I still have all the guts to build a 12000 rpm limited modify. Stroker rod, piston, cam, dual valve springs and carb just need a billet flywheel.
Those engines are awesome I have a 1978 4hp I wish I could mod it but there's no performance parts for it but I read you can bore it out and turn it into a 5hp
Gotta love these old B&S motors. Back when I was tinkerin’ around, EVERYTHING had either a Briggs or a Tecumseh motor on it. “Honda WHO?” 😝 As in, “Who would trust a JAPANESE motor?” lol Boy have times changed... 😏
emanuel diggs Yes, indeed...Harbor Freight Pedators. But I was referring to back in the ‘70s and ‘80s, when I was a young kid working on small engines. Honda single-cylinder engines were about as common and reliable as Liberal honesty and integrity. 😏
The block wasn't broke and welded it was welded to strengthen up the lifter area because of the high lift cam, if you didn't weld them and beef up that area they would break with the high lift cam
Rat Rod is an awesome kart. Definitely top 5 in my book. Can't wait to see what you do with modded briggs engine. I'm calling wheelies & maybe a new seat lol...
2:16 i'm crying laughing already! Sorry to laugh guy's, but this is why you do it! Keep sticking to the basics of the channel. These kinds of builds is why i keep coming back : )
You guys should convert one of the older Briggs opposed twins to horizontal shaft and use that on a cart. Someone else did that on YT and it was awesome.
The bracket from the top of the head to the carb is called a carb saver .... oddly enough it broke more carbs then it saved.. (novel idea).. if it came off a racing kart then it was likely a race built Briggs in methanol and it was more then likely just refreshed if it was that clean
The auto closed captioning calls the engine roar, “music.” While I’m pretty sure it’s confusing for those w/ hearing impairments, at the same time, it’s beautifully poetic.
hey I have question. I put a clutch on my 7hp go kart and it started to over heat, my chain was a bit loose but i don't that was the problem. Also my go kart is pretty heavy, and I was wondering what i could do to fix this problem. Any help would be greatly appreciated.
It would be great if you guys had intercoms inside your helmets and another one to communicate with each other like race teams. It would be good for safety and all around contact with each other while racing, testing, tuning and so on. I'm a big fan from Chattanooga TN. It would be great to drive up and meet at Busco Beach. After I get my 99 Honda CR80R Super Mini restored. I'd like to see the rail with a home made 2 speed transmission. If the built 670cc will stay together. Even a power adder on the 670cc, supercharger, turbo with a intercooler. Even a NOS Sneaky Pete system.

God bless ✌️
Id say its the guides from high use and rpm if you can use an insurt and drill out the old ones that should fix it. Love the vids.
These are some of the engines I work on daily at work. Love these little guys
Holy moly! I'm so glad to see one of these on your channel. In my hometown these are my go to, I build these engines on the regular for the dirt ovals my fellow hobbyists run on.
I race a highly modified flathead in ny state at dodge city speedway going into gold plate
FourEye where are you located...
Curious about an engine...no ..I dont race..
You have a briggs Raptor 3 engine. Can tell by the head having 3 tabs on it for the blower housing. I have a video from a couple years ago of our highly modified Flathead driving on my channel called "Limited Modified Briggs Flathead Go Kart"

Yep. Also, welding the block where the lifters sit is common. I have one out in the shop just like that.
I have a briggs raptor 3 set up on my go kart it sounds sick with a straight exhaust set up.

Nicolas Brown same
when he did the wheelie to get back i died 😂😂
Of course Ike breaks it lol
it'll be fine.
Looking forward to seeing this engine run when y’all get the parts, love those old school Briggs. Nice one guys!
That build is bad ass and the motor is free and i love the cam

That built Briggs sounds amazing although looking forward to what you guys can put together

the ratrod wagon is still one of my favorite rides y'all built, i love that thing xD
Love that you brought back the rat rod go kart. Also love that you are building a flathead briggs too!

Cool to see the wagon back! Looking forward to part 2!
Love it!! Bad thing is only available parts are online or if you're lucky in a junkyard but they tend to charge the same...been there done that!
The Rat Rod is the rason I subscribed to your channel. Glad to see it back!!!! Keep up the good work!
"Wheel fell off? Ahh, it'll be fine"
*HEAVY THROTTLE SOUNDS*
Monday and Wednesday are now my favorite days of the week. That things gonna be awesome when it’s on the kart.
Glad to see y'all doing some flatheads. Great ,reliable ,and fun little engines.
I am happy you all are. Doing the rat rod wagon .
That wheelie after the wheel came off was so casual and cool !
Can’t wait to see the drag rail again
Get an impact driver, the kind you hammer from Harbor Freight. Cheap and my favorite hand tool. Working on old engines and motorcycles it never disappoints.
DUDE!!! I used to build those Briggs engines. The valve tappets get material added to them so they won't break when you put in a high lift cam!

Offroad Outlaws 😱
RAT ROD kart is my favorite. Glad to see it back.
I think the cam is a 107SS cam from DynoCams which is a mild cam.
Looks like they still make it but out of billet instead so it’s probably pretty old.
Yea
You make this as I just got an old 5hp Briggs! YES
I would love to see you guys get another wagon and graft in an extension on the tub and put a low back bucket seat in it. Stretch that beast!!!
I have seen several modified briggs flatheads with tig welded reinforcements near the lifter bores.

10755 = 107.55 Horsepower on the dyno (at the crank, naturally).

I second that fuel tank idea
YESSS
That's like our old racing engines. Chain guard on the timing cover and it looked like our racing oil (Thor oils I believe). 5 hp Briggs made 13.6 hp.

I always wanted to build a go kart. But this video made me NEED to build one. Love this channel
The lifter area is welded to reinforce the lifter bores. That’s very common on these Raptor blocks.and that is a 107ss cam from Dynocams.
Very excited to see more of this build
Finally you guys are actually working on a flathead briggs engine. I’ve been waiting for this since you made the rat rod wagon
Ike's "click" sounds when torquing the bolts are one of the best thing on this channel
Been waiting for this video guys!!!!!
One of my favorite builds so glad to finally see this thing thing get some love
I have been watching for years this is the video that got me hooked. Today I finally subscribing. I challenge you to build another rat rode wagon. Then race them. Maybe do a 3 way build off. 3 rat rod wagons would be wild.
love seeing the Rat Rod Wagon on the channel
When you find a built engine..
"am i lucky or does the universe wana kill me"
GoPowerSports to the rescue...New Heavy duty spindles,Please.35mph and a wheel popping off..eek.Glad you were just doing 10,and on grass.
ok now im all excited to see this thing done, cant wait!!
I really enjoyed watching The build
I have an MANCO single seater with 5HP Flathead old Brigs with that same Raptor carb 👍🏻 Thing gets it !!
This is my favorite kinda content from you guys. 👍 making history with history.

Rat rod is definitely one of my favorite go kart builds! 😍
At 14:45 you can see a tiny flash through the fins where the spark plug is.
Those engines are awesome I have a 1978 4hp I wish I could mod it but there's no performance parts for it but I read you can bore it out and turn it into a 5hp
@Xaphan Vassago I couldn't find crap for it
Gotta love these old B&S motors. Back when I was tinkerin’ around, EVERYTHING had either a Briggs or a Tecumseh motor on it.
“Honda WHO?” 😝 As in, “Who would trust a JAPANESE motor?” lol
Boy have times changed... 😏
most of the motors they use arent even japanese, there chinese copies of honda engines
emanuel diggs Yes, indeed...Harbor Freight Pedators.
But I was referring to back in the ‘70s and ‘80s, when I was a young kid working on small engines. Honda single-cylinder engines were about as common and reliable as Liberal honesty and integrity. 😏
😁😁😚 yay I love the ratrod wagon. Its so great, love the channel guys your still doing great!!!!!!!!!!! Can't wait for what's next
The block wasn't broke and welded it was welded to strengthen up the lifter area because of the high lift cam, if you didn't weld them and beef up that area they would break with the high lift cam
I've seen videos of people using smog pumps from cars as small engine superchargers. That would be cool to see done!
This is my favorite cart you guys have
She got a CAM inner boys!
Rat Rod is an awesome kart. Definitely top 5 in my book. Can't wait to see what you do with modded briggs engine. I'm calling wheelies & maybe a new seat lol...
I literally laughed so hard out loud! Awesome video! Loving the channel, as always.
Love the wagon guys.
That thing is so cool and well -made- designed
2:16 i'm crying laughing already! Sorry to laugh guy's, but this is why you do it! Keep sticking to the basics of the channel. These kinds of builds is why i keep coming back : )
You guys should convert one of the older Briggs opposed twins to horizontal shaft and use that on a cart. Someone else did that on YT and it was awesome.
Don't have to convert them, horizontal shaft opposed twin Briggs are fairly easy to come by.
The welds on the valve portion of the block are required on flathead motors for the aftermarket cams and spring.
The bracket from the top of the head to the carb is called a carb saver .... oddly enough it broke more carbs then it saved.. (novel idea).. if it came off a racing kart then it was likely a race built Briggs in methanol and it was more then likely just refreshed if it was that clean
The auto closed captioning calls the engine roar, “music.” While I’m pretty sure it’s confusing for those w/ hearing impairments, at the same time, it’s beautifully poetic.
That definitely smokes! I will admit it isn't good for the engine, but it looks awesome!
hey I have question. I put a clutch on my 7hp go kart and it started to over heat, my chain was a bit loose but i don't that was the problem. Also my go kart is pretty heavy, and I was wondering what i could do to fix this problem. Any help would be greatly appreciated.
It would be great if you guys had intercoms inside your helmets and another one to communicate with each other like race teams. It would be good for safety and all around contact with each other while racing, testing, tuning and so on. I'm a big fan from Chattanooga TN. It would be great to drive up and meet at Busco Beach. After I get my 99 Honda CR80R Super Mini restored. I'd like to see the rail with a home made 2 speed transmission. If the built 670cc will stay together. Even a power adder on the 670cc, supercharger, turbo with a intercooler. Even a NOS Sneaky Pete system.
Finally some flaty action!! Makes me want to revive mine
Love the old school stuff!!!
Breaks spindle....rides wheelie into the shop....well played sir, well played.👏👏👏
