I loved this video!!! Not only are you teaching others but you're helping someone who has worked hard for something and can't find the answer. Thank you for doing this Red Beard.
Working hard would mean the person read at least SOMETHING about engine assembly. I think what you meant was helping others that spend hard after watching a UA-cam video
Super cool of you to take on this guy's engine and investigate. Kudos for donating your own parts as well. God has blessed you, and now Jose's engine will be blessed with the ol' Red Beard touch!
Awesome video, and kudos to you for donating the block and crank of the test bed. Hats off to you for taking the time to tear it down, explain, and making it right for the guy who sent it in.
Everyone makes mistakes and if they don’t it means there not doing anything, I work on multi million dollar aircraft and I can tell you mistakes are made all the time……….they just are a lot more costly when they do happen
I have to say RB, OUTSTANDING channel! You guys are real mentors to the next generation of knuckle busting gear heads. This video should be shown to all the grease monkeys in school and I mean that in a very positive way. I can still remember when I was in shop class tearing down the old Briggs engines and the first time it fired up after putting it back together, very rewarding feeling. You have so much respect for this hobby. Over the top channel guys!
I was told at a really young ages that Knowledge is useless if you don’t share it. I Appreciate your honesty and understanding but mostly your honest intentions to help a fellow young builder.
Sir, you have earned my utmost respect 👍💯. Thank you for helping Jose out. We need more people like you to teach these skills . Alot of guys are very selfish about sharing their mechanical knowledge. Just an awesome job man.
This has been one of my favorite videos, super enjoyable. There are some things that Jose has done that I have also missed in the past. Really think this should be a regular thing or video series. Especially if you’re helping younger people with engines and parts. Amazing video series that I would definitely watch. God bless you and prayers for Jose’s engine block… lol
You should do this as a episode series. Get people’s projects that are new to engine building and having issues and go through it and show where they went wrong and how to address the issues. I think this is just as beneficial as showing how to build engines correctly. Reason I say that is we only see a guy having everything going right. Only time we see guys having issues is when something breaks.
Hey bud, just started watching your vids, found you through Cars n Cameras vids. I think it's awesome you included your subscriber and helped the guy out with his engine. That's a great personal touch that I think is missing from UA-cam. Shows you genuinely care and go out of your way to spread the fellowship beyond just being a mouthpiece on the net. Much respect, you earned a subscriber here. God Bless.
I’m from the southeast and I’ve found a little smaller jet will out perform larger ones If 110 is good central us 95-100 is good in the south !! I’ve found this out the hard way.. save yourself a headache start smaller and if the engine just needs more then step up one size at a time. Don’t let the pilot whip you !
I used to work for ARC racing in the machine shop and you wouldn't believe how awesome it is to see all those machines running at once.Theres a great group of guys that make those parts for everyone. Shout out to PJ, Swayze, and Brian! You should do a shop tour of their facility down here in Albany Ga soon
You can definitely use a standard compression tester on these engines the compression release does not effect the results because most modern compression guages have a check valve and the engine still makes compression before the compression release releaves it I have checked compression before and after removing a compression release on my road to horse powers and it was the same useing a standard harbor freight compression guage
You truly are an amazing builder. I just finished this build off of the 224 full stage 4 build and it was a true relief to see it run. If i have any issues i will be refering directly to these videos. Thank you so much for the time and effort you invest in what you do. Next is a V-Twin full billet build
Because I've been watching you for years,and have seen what you do with it,I have 5 different cans of PB Blaster products,and you're right about them being good. Thanks for showing this 'tear down and checklist' for our builds.Jose did do some pretty good work on it,and yes,we all forget something along the way.We don't forget twice after the lesson's learned.Some of the metal crumbs are probably cylinder lining and the skirt.
I went down a road like this kind of similar. I can't 100% tell, but that piston looks like a mono ring piston. I also ran one of those and had severe blow by in no time. The next rebuild i did on mine i switched to a dual scraper ring Wiseco piston and haven't had any issues since. Hope this gets to ya in time Red Beard!! I do believe between a mono and dual scrapper ring Wiseco piston; pin heights are different. if I remember correctly from a 3.707 to a 3.595 length rod, factory crank. Happy Building !!
Crazy how a simple problem can get a nice build hung up. My hemi had a valve piston make out session and still ran with a bent valve. I tried for hours to re-tune it before deciding it was time to strip it down and start building it from the ground up again. Sometimes when thing don’t work you gotta just admit that something’s wrong and restart. Saves you a lot of frustration at the expense of some effort
This is cool content. My family owns an automotive repair shop and one of our guys was hired young with not much experience. My dad and I both have taken a lot of time with him and it has been awesome watching him grow in this industry. Like you said the only way to actually learn this stuff is to do it, no amount of video watching or book reading will substitute actually getting your hands dirty.
Excellent video…absolutely love the level of detail and explanation. Cant wait for part 2…maybe you can Jose to do a follow up video when he gets it back.
Cannot thank you enough for making these videos !! my son and myself have gotten into kart racing in my Five-year-old grandson is our driver. We have just about completed our first season of racing, and I am wanting to get into building his motors. I am extremely thankful that I found your channel. I have gone back and watched a couple of your videos, but I am most definitely starting at the beginning of the road to horsepower. Thank you again and PLEASE keep the videos coming !!👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻
One con to the dingle berry ball hone is if the cylinder has uneven surfaces like pits from corrosion, the balls will follow those uneven surfaces. Generally I prefer to use the flat stone type as they’ve got a better chance of evening out the bore. Just my opinion from experience.
A ball hone is meant for deglazing the cylinder. It's not meant to use to get cross hatching back.. The correct way is to use a straight hone, like a Amco, Sunen,ect but a straight hone is what you want. Otherwise if your cylinder is out of round it will show where it's has low spots and when you are done you know it's perfect.. even after boring out a cylinder you always take the last few thousands out with a straight hone... NEVER A CHEAP BALL HONE... Those are about 35 to 70 dollars and a good straight hone is around 5 to 6 hundred dollars...not trying to be a smart ass but like you said after doing something wrong and then figure it out you learn... so hopefully you will do some research and you will find out what I have Said is correct.. you will never see a good machine shop ues a ball hone and then put it together. We use a ball hone first to clean the cylinder and deglazing a cylinder before assembly you use a straight hone to get proper clearance and a good cross hatch.... and if you do it your way or how I explained. And do a leak down test on the cylinder your way and it will have more blow by a lot sooner than if you used a straight hone.. this is a fact and thousands of engine builders will back it up... take care and have a great day....Bob....
Greetings from Texas! Great video. Good example of what to look for when performing a high performance build using off the shelf parts. Many of us do not have the tools to do our own custom work and this is the only way we can build a hot engine. Overall I believe that Jose did a good job, just a few minor things to remember for his next build. Hats off too Jose for asking for help from a master builder instead of pushing a bad build due to a damaged block. Happens to us all. Thanks for taking this on, Greg. It teaches us more that just how to build engines.
classic hotrodding, "build it, blow it up, and build it back faster than it was before" otherwise known as "Trial And Error" you learn from your mistakes, no shame in trying and failing, the issue occurs when you fail to Try, Jose you tried something new, and you put yourself out there, no shame brother this is how you learn, thank you Greg for showing us all what items to keep an eye on and out for, and as a wise man once said "you don't know what you don't know" i hope Jose enjoys a fun hobby and isn't disheartened by failed parts, trying and failing has no shame, thats a valuable learning tool, stay safe out there y'all
you never learn if you dont try. hopefully this encourages him to learn more. need more people willing to teach and help rather than put others down. subscribed to this channel for sure.
Great job, it is really tough to spend the money and take your time to do a clean build, all you want to do is get that engine running, but youngsters, take heed, keep it clean...
i love tbe road to hp series so much. youve got me inspired enough to start building. my own cart and bike. im building a 212 swap rt100 frame. i always come to your channel for advice on things im tryin to do
Awesome. My son and I are just getting into this hobby together. I love to see videos that help others learn things to do and not to do. We all learn from each other. Thanks for posting all of your videos. Can’t wait to see the outcome.
I know you spent a lot, a lot of your time on this, more than anyone could expect. You did not miss a thing while softy sharing your knowledge and your wise decision making process. I spent 30 years as an master auto mechanic and I would have loved having you in the bay next to mine.
When I seen the bore after the first pass I was just screaming noooo.... I just knew the dingle dangle hone wasn't gonna get it. But Jose I give you credit must ppl wouldn't even try to build a stage one kit
You are so right about cleaning everything. Ive been building for many years from single cylinders to 900hp 410 sprint car engines. On the small engines, I have a dishwasher that I bought from the Used Appliance store after I clean everything in the parts washer, I run the block and all parts in the dish washer with very hot water. Gets super clean for final assembly. You are probably the most informative on UA-cam. There is a lot of BS on the Tube but my opinion you're the best yet. Enjoy your Holiday. PS...I have an EZ Bore boring machine tp do flatheads and Animal OHV blocks. When honing don't get it done.
Yes it is. After the solvent, the washer for final wash for assembly. I found and old wringer type washing machine to clean shop towels. instead of tossing them and buying new
Really decent of you to help Jose, it's great for us that you agreed to do the autopsy and share it with us. With all this work, I'm surprised that he's using the weenie little carb. Even the fake 22 Mikuni would be a huge improvement, particularly if he matched the ports (a 40% increase!) and then spent some time tuning it. Watching #2 now...
I’ve been obsessed with mini bikes since I was a kid. Always wanted a CT200u as a kid but my family just never got it was to much money. I’m now 19 with 2 good paying jobs and have a RT200 coming in the mail right now! First thing I’ve ever had with an engine but I’ve watched probably almost every YT video about mini bikes. This video is easily the most helpful and well explained video I’ve seen. It’s perfect because my bike is coming with a 196 and I’m planning on buying a predator and going on from there.
This is a wonderful video. God Bless you brother for helping this young man out. If more men were like you just think of how good this world would be. Lets all look out for eachother.
FYI On the billet rockers the pushrod length has nothing to do with geometry as the adjuster is on the pushrod side not the valve side. Pushrod length just changes where your adjuster sits in the rocker. Geometry is set by the valve tip height.
So, the wear or scoring of the piston can all be related to the loose nut on the carburetor. When you pulled the spark plug, you indicated it looked like it had been running rich. And when you found the loose carb nut, there was fuel puddling on the gasket surfaces to that side. This excessive rich condition can cause cylinder wash, where the excess, unburned fuel will wash away the oil lubricating the cylinder walls and cause the pison to be scored as well as the cylinder walls (this Condition usually damages piston rings aswell). Although, its probable he wasnt very clean with his drilling and tapping, its my belief all of the issues found (metal in the oil, scored piston, scored rod bearing) stemed from the carburetor being impoperly secured. Id be willing to bet his oil had a smell of fuel in it, which would confirm my theory. Great job on the tear down and explanation of everything.
Never use a drill bit to check jet sizes. Jets are not straight through, they are hourglass shaped. You may have found a bit that fits the opening, but running it through the center you eliminated that throat of the jet. Even on a little pin vise hand/finger drill. I have fixed many motorcycles, dirt bikes, ATVs, etc, that wouldn’t run because someone did some mods and went cheap and used a 1.20 mm drill bit to make a 120 jet. Put proper 120 jets in it and it ran perfectly fine. Same gas and everything.
The carb in this video is a stock carb. Guys have been opening the main jets on these carbs for many years. If you buy a larger main from ARC racing you are getting a jet that they opened up with a drill bit. I've opened up a lot of them and they work fine.
My 420cc stripped threads on one of the carb studs....causing it to run lean. Next oil change has glitter in the oil. Engine still running and sounds good but running lean causes heat and accelerates wear. The same happened to his. With clean oil and the carb vacuum leak fixed, it'll probably run for a good while.
Great disassembly video. If the old gasket material wasn't removed, wouldn't that throw off end play clearance? Never use steel razor blades on aluminum surfaces. Brass, or plastic scrapers and avoid the gouges and scratches.
cleanliness is godliness. If the carb was lean because of the jet/emulsion tube plus the possible vacuum leak, could it have possibly ran lean this way and done damage to the piston as well. So hopefully the rod didnt get slightly pounded and bent.
My grandfather has always tinkered with small engines of all types. I just clicked on this because of slight interest I've played with gocarts at his house growing up. I watched this whole video and it has me wanting to fully build and engine for a gocart with my sons. A lot cheaper than building a car engine 😂😅. I'm interested to see the next video I've never pictured a Dyno for a small engine 😮...
Forged pistons, such as Wiseco, require extra bore clearance for the expansion of the piston. Factory hyperuetectic pistons do not expand at the rate of a forged piston. Wiseco pistons tend to have a lot of taper from the skirt to the top ring land; I would measure to ensure that most of the aluminum didn't come from the piston. More than likely, the bore is tapered, and piston clearance was not checked during assembly. Oil rings intersecting the pin bore are typically used in long rod or stroker applications.
The best advice I can give is double check everything then recheck it. Also the engine teardown area keep it clean . Remember we all do dumb things from time to time.some from learning new stuff some from rushing. Just learn from your mistakes and you will be fine . Now I was rushing one time I forgot to put in the c clip on a pin that holds the piston rod to the piston well that build did not go well . What I learned is don't get in a rush make sure to check everything.
These videos are so incredibly helpful. I’ve worked on german cars my whole life, and I think I learn more watching your videos, then spending a day in the shop working on a $20k engine. All of this small engine stuff is so interesting to me and I really which I had started here😅
nothing wrong with making mistakes thats how you learn. in high school my first year in shop class we toredown a 212 we had to take it completely apart like you did here and put it back together. now i had an upper hand there because i had years of building racecar engines by then. but when it came to building a 420 for my golfcart ive screwed a few things up. my excuse now is that im now working with one hand. the way i save money building small engines is to play the market and bulk buy parts when the usd is low and cad is nigh
Can polish scratches out of any piston with out any issues. Hone cylinder and new rings an buff piston. Rod bearing shinyness is just a coating consider it a break in coating. The shine can be fully worn off and it will still spec out completely fine. If you can physically feel scratches that’s no good but short of that the lack of shine isn’t anything to worry about. More holes in the emulation tube means it will run leaner longer but wide open top rpms will be same fuel ratio as less hole emulation tube. The rings should absolutely be replaced over anything else
Excellent video, I love how you are teaching attention to detail. Many times that is what trips people up when doing projects. Showing all of your steps was a great way to teach.
First time watching any of your videos “showed up on my feed”. I know you said you’re a professional. I’m no expert on the engine you’ve built But I’ve built my Subarus engine “now making 1000+whp”. Only suggestion I have is use ATF on a blue shop towel when cleaning the cly after honing it. Yes the brake cleaner works but ATF is just that much better. Flip the towel over and keep going until the towel stays red like the fluid then you know at that point that cly is clean. Love the video can’t wait for pt2 I have no idea what this engine is for or what it’s used in. But I’m now tempted to buy and build one 😅
I love when I come across a super informative channel that's interesting to watch. Not to mention how good of a guy Greg seems to be. Saw the mud motor vid and I've been watching em all.
Great idea for teaching us newbies! Jose did a lot right, but it was missed details that torpedoed the build. Greg do you have a Vacuum Valve seat tester? I used a portable Serdi brand at work (yeah high dollar for sure!, but much cheaper brands are available.) The big advantage is that the head can stay on the block & only the manifolds need removal to test valve sealing condition at the seat. Thanks RBG !
Hey, good on Jose for doing as much as he did. Thank you for taking this engine on. It’s great content and shows us how detailed you can be on a build like this. Also how easy it is to miss these things. All my best.
You are the best, if the world just had more people like you. There would be no wars and life would be great. You set the example of less greed and more love. God bless and give hugs to all your friends from me.
Im new to this channel and im in love with it! I recently started working on 3 free karts and 4 engines. Luckily for me my best bud is the best small engine tech in my area. Before go in on these 4 kart engines ive only been coached on 2 chain saw builds and a lawn mower build. It's awesome to find a channel with answers to the questions i have. Thank you!
Awesome video thanks for doing this. Really liked seeing your troubleshooting process. And thank you Jose, I know it was probably frustrating for you but we all get to learn from your experience.
It truly was but hey you get threw things sometimes all you need is a little push , glad my troubleshoots can lead someone else in the right path thanks to RedBeard and his wife 🙏 - Jose
Yooo man Thank you so much Greg it’s truly a blessing for you to help me out man god bless 🙏 - Jose
We need to see the machine that goes in when it's ready.
For sure I’m working on a go kart frame it’s going on a Go Kart -Jose
@@941GKFAMILY🙌
@@941GKFAMILY Greg welds too so can you break that also so we can learn more? ROFL
I am kidding, I wish you the besr of luck with it.
@nubswithguns hmmm 🤔i just might… 😂 no I’m kidding red has helped me a lot already to me it’s more then enough
No hate on Jose. Everyone starts somewhere, that's why we learn from our mistakes and don't give up on what you love to do
Amen brother -Jose 🙏
100%!! Learning and teaching is how this hobby keeps going. Never be ashamed to learn, but always be willing to teach.
10000000% in order to know things you need to learn if it means mistake are made
When I watched this, I started remembering some of the mistakes I’ve made on cars and small engines over the years. A LOT of them.
@chuckwalker4149 same some were major some were minimal
Greg you should do motors like this from time to time. We all could learn from mistakes and help with diagnostic . More power to Jose
I agree
I agree
I loved this video!!! Not only are you teaching others but you're helping someone who has worked hard for something and can't find the answer. Thank you for doing this Red Beard.

Super cool of you to take on this guy's engine and investigate. Kudos for donating your own parts as well. God has blessed you, and now Jose's engine will be blessed with the ol' Red Beard touch!
Amen to that sir 🙏
Truely one of your BEST videos. Awesome to see the breakdown & your analysis of the engine & why it wasn't performing.
Awesome video, and kudos to you for donating the block and crank of the test bed. Hats off to you for taking the time to tear it down, explain, and making it right for the guy who sent it in.
this is why i watch your videos helping this guy out and teaching others is all good
Great video. Thanks to Jose for putting himself out there!
Thanks to you to brother - Jose
Everyone makes mistakes and if they don’t it means there not doing anything, I work on multi million dollar aircraft and I can tell you mistakes are made all the time……….they just are a lot more costly when they do happen
You are just an all around good guy Greg. Thinking of others and helping people out is where life is most rewarding.

Let he who is without oil throw the first rod. Lubricants 14:3.
🤣
This was a really great video. Nice to see the problems someone came across on a first build.

You were close Jose. Don’t give up brother. You got this.
Thanks man Gregs blessing and all you guys comments it’s most deff a huge motivation to push further - Jose
Because I've been watching you for years,and have seen what you do with it,I have 5 different cans of PB Blaster products,and you're right about them being good.

Great job, it is really tough to spend the money and take your time to do a clean build, all you want to do is get that engine running, but youngsters, take heed, keep it clean...
I did rush for the fact I just wanted it done I took it apart and it sat untill parts came In - Jose
i love tbe road to hp series so much. youve got me inspired enough to start building. my own cart and bike. im building a 212 swap rt100 frame. i always come to your channel for advice on things im tryin to do
Awesome. My son and I are just getting into this hobby together. I love to see videos that help others learn things to do and not to do. We all learn from each other. Thanks for posting all of your videos. Can’t wait to see the outcome.
I know you spent a lot, a lot of your time on this, more than anyone could expect. You did not miss a thing while softy sharing your knowledge and your wise decision making process. I spent 30 years as an master auto mechanic and I would have loved having you in the bay next to mine.
When I seen the bore after the first pass I was just screaming noooo.... I just knew the dingle dangle hone wasn't gonna get it. But Jose I give you credit must ppl wouldn't even try to build a stage one kit
Loved this video. I’d like to see more like it. Great job Greg.
You are so right about cleaning everything. Ive been building for many years from single cylinders to 900hp 410 sprint car engines. On the small engines, I have a dishwasher that I bought from the Used Appliance store after I clean everything in the parts washer, I run the block and all parts in the dish washer with very hot water. Gets super clean for final assembly. You are probably the most informative on UA-cam. There is a lot of BS on the Tube but my opinion you're the best yet. Enjoy your Holiday. PS...I have an EZ Bore boring machine tp do flatheads and Animal OHV blocks. When honing don't get it done.
The dishwasher idea is genius. like a budget steam cleaner. I'm going to look into getting one for the shop.
Yes it is. After the solvent, the washer for final wash for assembly. I found and old wringer type washing machine to clean shop towels. instead of tossing them and buying new
We love Red beard and his beautiful wife we never see that’s holding the camera so so steady for all us viewers! 🤙🏼
Thanks for sharing,…..your positive input means so much to so many. You are a great teacher,…Good Stuff 👍😎🙏
Really decent of you to help Jose, it's great for us that you agreed to do the autopsy and share it with us.
With all this work, I'm surprised that he's using the weenie little carb. Even the fake 22 Mikuni would be a huge improvement, particularly if he matched the ports (a 40% increase!) and then spent some time tuning it.
Watching #2 now...
I’ve been obsessed with mini bikes since I was a kid. Always wanted a CT200u as a kid but my family just never got it was to much money. I’m now 19 with 2 good paying jobs and have a RT200 coming in the mail right now! First thing I’ve ever had with an engine but I’ve watched probably almost every YT video about mini bikes. This video is easily the most helpful and well explained video I’ve seen. It’s perfect because my bike is coming with a 196 and I’m planning on buying a predator and going on from there.
This is a wonderful video. God Bless you brother for helping this young man out. If more men were like you just think of how good this world would be. Lets all look out for eachother.
FYI On the billet rockers the pushrod length has nothing to do with geometry as the adjuster is on the pushrod side not the valve side. Pushrod length just changes where your adjuster sits in the rocker. Geometry is set by the valve tip height.
So, the wear or scoring of the piston can all be related to the loose nut on the carburetor. When you pulled the spark plug, you indicated it looked like it had been running rich. And when you found the loose carb nut, there was fuel puddling on the gasket surfaces to that side. This excessive rich condition can cause cylinder wash, where the excess, unburned fuel will wash away the oil lubricating the cylinder walls and cause the pison to be scored as well as the cylinder walls (this Condition usually damages piston rings aswell). Although, its probable he wasnt very clean with his drilling and tapping, its my belief all of the issues found (metal in the oil, scored piston, scored rod bearing) stemed from the carburetor being impoperly secured. Id be willing to bet his oil had a smell of fuel in it, which would confirm my theory. Great job on the tear down and explanation of everything.
This is the best video I have seen in a long time. It’s awesome to see you guys go above and beyond for one of your followers. I’m now a fan!
Never use a drill bit to check jet sizes. Jets are not straight through, they are hourglass shaped.
You may have found a bit that fits the opening, but running it through the center you eliminated that throat of the jet. Even on a little pin vise hand/finger drill.
I have fixed many motorcycles, dirt bikes, ATVs, etc, that wouldn’t run because someone did some mods and went cheap and used a 1.20 mm drill bit to make a 120 jet.
Put proper 120 jets in it and it ran perfectly fine. Same gas and everything.
The carb in this video is a stock carb. Guys have been opening the main jets on these carbs for many years. If you buy a larger main from ARC racing you are getting a jet that they opened up with a drill bit. I've opened up a lot of them and they work fine.
My 420cc stripped threads on one of the carb studs....causing it to run lean. Next oil change has glitter in the oil. Engine still running and sounds good but running lean causes heat and accelerates wear. The same happened to his. With clean oil and the carb vacuum leak fixed, it'll probably run for a good while.
Great disassembly video. If the old gasket material wasn't removed, wouldn't that throw off end play clearance? Never use steel razor blades on aluminum surfaces. Brass, or plastic scrapers and avoid the gouges and scratches.
CONGRATULATIONS ON 400,000 Subs
Thank you! Couldn't do it without all of you!!
That's a two stroke piston with that single ring setup only theres no windows on each end for intake and exhaust to flow through
Such a great vid and good deed you did for the young man. Very lucky have ur engine rebuilt by RBG
Big Bearded Dude doing Jose a solid! Much respect, brother!
Cool of you to help homey out. 👍
cleanliness is godliness. If the carb was lean because of the jet/emulsion tube plus the possible vacuum leak, could it have possibly ran lean this way and done damage to the piston as well. So hopefully the rod didnt get slightly pounded and bent.
My grandfather has always tinkered with small engines of all types. I just clicked on this because of slight interest I've played with gocarts at his house growing up. I watched this whole video and it has me wanting to fully build and engine for a gocart with my sons. A lot cheaper than building a car engine 😂😅. I'm interested to see the next video I've never pictured a Dyno for a small engine 😮...
Forged pistons, such as Wiseco, require extra bore clearance for the expansion of the piston. Factory hyperuetectic pistons do not expand at the rate of a forged piston. Wiseco pistons tend to have a lot of taper from the skirt to the top ring land; I would measure to ensure that most of the aluminum didn't come from the piston. More than likely, the bore is tapered, and piston clearance was not checked during assembly. Oil rings intersecting the pin bore are typically used in long rod or stroker applications.
The best advice I can give is double check everything then recheck it. Also the engine teardown area keep it clean . Remember we all do dumb things from time to time.some from learning new stuff some from rushing. Just learn from your mistakes and you will be fine .
Now I was rushing one time I forgot to put in the c clip on a pin that holds the piston rod to the piston well that build did not go well . What I learned is don't get in a rush make sure to check everything.
That's great Greg sharing knowledge to a person new in the hobby , we all learn .
These videos are so incredibly helpful. I’ve worked on german cars my whole life, and I think I learn more watching your videos, then spending a day in the shop working on a $20k engine. All of this small engine stuff is so interesting to me and I really which I had started here😅
Great video! Currently building my 212 and I can’t wait to finish it.
Excellent and high quality videos! These are great sources of information and family friendly! Much respect to Greg and his entire family
Excellent Vlog. 100% should be doing more of these. Learning way way more with this engine over a perfect build.
I appreciate you for this, it’s why I keep watching this channel because this is someone just like me that you inspired
You're a class act Mr. Red. Mr. Beard is pretty cool too.
nothing wrong with making mistakes thats how you learn. in high school my first year in shop class we toredown a 212 we had to take it completely apart like you did here and put it back together. now i had an upper hand there because i had years of building racecar engines by then. but when it came to building a 420 for my golfcart ive screwed a few things up. my excuse now is that im now working with one hand. the way i save money building small engines is to play the market and bulk buy parts when the usd is low and cad is nigh
Milwaukee should sponsor this Red Beard's Garage!
Can polish scratches out of any piston with out any issues. Hone cylinder and new rings an buff piston. Rod bearing shinyness is just a coating consider it a break in coating. The shine can be fully worn off and it will still spec out completely fine. If you can physically feel scratches that’s no good but short of that the lack of shine isn’t anything to worry about. More holes in the emulation tube means it will run leaner longer but wide open top rpms will be same fuel ratio as less hole emulation tube. The rings should absolutely be replaced over anything else
Excellent video, I love how you are teaching attention to detail. Many times that is what trips people up when doing projects. Showing all of your steps was a great way to teach.
Nice dissection & commentary!, thanks for sharing !
Great idea for a video! Seriously man A-1. I'm a bit of a clumsy dumby, so being able to witness mistakes I'd make is wonderful. Thank you
Good job, very nice of you to donate time and part’s. I think you need a home boring machine for small engines. Bound to be a setup for a drill press.
First time watching any of your videos “showed up on my feed”. I know you said you’re a professional. I’m no expert on the engine you’ve built But I’ve built my Subarus engine “now making 1000+whp”. Only suggestion I have is use ATF on a blue shop towel when cleaning the cly after honing it. Yes the brake cleaner works but ATF is just that much better. Flip the towel over and keep going until the towel stays red like the fluid then you know at that point that cly is clean. Love the video can’t wait for pt2 I have no idea what this engine is for or what it’s used in. But I’m now tempted to buy and build one 😅
Im working on a go kart frame I’m putting it on - Jose
Good vid!!!
Nice to see you help a dude out.
Looking forward to seeing how it runs when you're done.
I love when I come across a super informative channel that's interesting to watch. Not to mention how good of a guy Greg seems to be. Saw the mud motor vid and I've been watching em all.
Thank you Blaster!
Great idea for teaching us newbies! Jose did a lot right, but it was missed details that torpedoed the build. Greg do you have a Vacuum Valve seat tester? I used a portable Serdi brand at work (yeah high dollar for sure!, but much cheaper brands are available.) The big advantage is that the head can stay on the block & only the manifolds need removal to test valve sealing condition at the seat. Thanks RBG !
Shout out to Jose for building that engine and being willing to learn. Great job Red beard garage for another great video!
Great video! Looking forward to the 2nd part.
Hey, good on Jose for doing as much as he did. Thank you for taking this engine on. It’s great content and shows us how detailed you can be on a build like this. Also how easy it is to miss these things. All my best.
You are the best, if the world just had more people like you. There would be no wars and life would be great. You set the example of less greed and more love. God bless and give hugs to all your friends from me.
Amen 🙏- Jose
Im new to this channel and im in love with it! I recently started working on 3 free karts and 4 engines. Luckily for me my best bud is the best small engine tech in my area. Before go in on these 4 kart engines ive only been coached on 2 chain saw builds and a lawn mower build. It's awesome to find a channel with answers to the questions i have. Thank you!
Awesome video thanks for doing this.
Really liked seeing your troubleshooting process.
And thank you Jose, I know it was probably frustrating for you but we all get to learn from your experience.
It truly was but hey you get threw things sometimes all you need is a little push , glad my troubleshoots can lead someone else in the right path thanks to RedBeard and his wife 🙏 - Jose
