people doing diy project in youtube should exactly follow your way to do it, clear video, no noisy music and does not have other bs unrelated to the project, good job kid.
Best DIY video I have ever watched. Not just showing how to do something, but also explaining exactly what everything is. I learned in this one video everything I had questions about. Anyone who is looking to mod a 212 or 420 should watch this video before even looking at a screw driver or drill. Thank you, sir!
Thank you for the video bud. There's a lot of 420 mod videos out there but yours was by far the best and easiest to follow and I appreciate you sharing your time and knowledge 👍🏻
Get yourself a valve spring tool and save yourself potentially serious injury with either the spring or retainers shooting up into your face, or the vice grips pinching the devil out of your thumb. You can also save a fishing expedition into the crankcase for the retainers that way as well. You can also get a truck brake spring driver (used on drum brake barrel shaped springs that hold the shoes to the backing plate.) It has a screwdriver handle and shank with an open ring at the end that compresses the spring as you push down, while allowing you to rotate the retainers. The retainer tool for trucks should be the right diameter to cup the spring and the retainer cup on top of your valves so you can place the retainers in the cup and stem of the valve.
It is practice to put air pressure into the sparkplug hole to keep the valves seated while replacing the valve springs. Very nice video, thanks for sharing.
Thank u enbiggen hole is not engineering. This kid is not an engineer. He is doing everything u should never do unless you are trying to kill a motor. No reason to diable low oil sensor EVER!
@@TrapperAaron It is true all the modifications he is doing to this motor can decrease engine life. But he stated that he is doing this for performance, and mods made for more power are always at the risk of less engine life. He also explained the reason for disconnection of the low oil sensor. It is at one side of the block, and a hard corner will, through centrifugal force, throw the oil away from the sensor and kill the power. These motors are made for stationary use and steady power demand, totally different from what he is preparing this engine for. And if he does not realize this can shorten engine life, he will soon learn.
Watching you using that vice-grip to push down on the spring, I just was waiting to cringe when it slipped and either smashed your finger or sent the vice-grips into your face, glad it all went good!
It’s refreshing following a video without the presenter trying to be a comedian (and in some cases with friends) or blaring music in the background. Well done! Good, clear video capture as well. 👍
Took me years and years to learn how to hold a drill straight and plumb when hand drilling a hole. I’m 50 now and can only now promise that I can drill a hole straight in! Don’t let that bother you especially if it WORKS when you’re done.
I spent an hour looking for one of my keepers didn't have a good grip trying to put the spring back in and shot out with everything in it I almost cried. Wish I woulda watched your video first.
great video! instead of removing governor, cant you just disconnect the linkage? instead of removing low oil sensor, cant your just disconnect the wire?
u did a nice lil video here. u taught me something. now ill have no problems doing these same mods when its time. im impressed. i love working with engines and metal. like welding. i worked at a lil aluminium boat factory and taught myself how to tig and mig aluminium. even anodized aluminum. i thought aluminium was tricky to weld. took a welding class in school to weld mild steel and iron. i have alil mig, tig and stick welder combo. i can even gas weld. again. nice vid lil brother. never stop learning and showing ur skills. u have a nack at it
Just throw that paint! Too cool. Enjoyed it. Natural communicator, you are. Well done. I see a video series for sale in your future. A lion in the chase never looks back
I have a 420 in a Ducar wood chipper and was wondering why I couldn't get full throttle --- it was the governor -- thank you as your video helped explain it!!
The filter I bought came with the adapter and a hold down for the choke, the spacer (I bought separate) had the correct holes in it. Also came with a bigger jet...I can't recommend using the bigger jet , the engine runs better and comes off of choke faster with the OEM jet it came with.
Just to let you know the other method of holding the valves in place is air pressure by installing a modified fitting with a air hose hooked to your compressor to the spark plug hole.
Dude there is so much horrifying and terrible info in this video and ur concered about some drill and tap debris? This video i pray is really a joke. Like what not to do to any small motor ever.
Thanks for an informative and nicely produced video. One question, though: couldnt you just replace the spring from the throttle arm to the governor arm to raise the rpm while thus raising the max rpm while keeping the limiter function? Thx.
If you’re worried about not being able to get all the backer rod (sponge thingy) out of the cylinder, you can use an air hose fitting to screw it into the spark plug hole and apply 100psi air to hold the valves in place. I’ve done this multiple times when replacing valves springs on Chevy LS motors while it’s still in the truck. This was a great video, and I doubt you’ve put it on a dyno to see the power increase, but do you have any idea how much power increase you got, or how high you can rev the rpm’s?? I know the factory governor had it at 3600 rpm’s.
Could fill the cylinder w air through the spark plug hole compressing when removing n installing the valvebsping n valve spring seals . But all in all. Awesome job
again, this kid is great! I like the custom adapter for the air filter. also props to the paint job. that had me laughing! keep up the good work real steel.
You can use air pressure to hold the valves back using a compression guage hose & air hose nipple ,Get yourself a round brake anchor pin tool great for doing valves too .
Good job. Those areas where small parts fall into are called "hell holes"...always plug/cover them before taking stuff apart that could fall in there....I think you figured that out though.
Hello, great vid. Very helpful info. Where can I get upgrade valve springs? I have a 16 hp single cylinder like your one but I can't seem to find any. Do you think the 35 lb springs would work for this engine too? Thank you for your time.
brasil- rio de janeiro: faltou ligar , pra ouvi o som! ( missed calling to hear engine sound!) I saw that you are building a motorcycle with this engine! congratulations .. you are a smart guy!
[ On the choke lever ] i drilled a small hole in the lever like you would for a screw. Then i made a few grooves angled downward in the shaft. I mixed up a little JB Weld ,fingered it into the shaft grooves then shot some into the lever with a crack filler syringe. When i pushed the lever down some epoxy came out the top hole and i finger molded it over like a little cap. that was 10 yrs ago and it's still on there. PS i used my dremel for the grooves.. I knew if i tried to drill and tap that shaft i would F#%k it up..lol
THANK GOD you bought a pre-drilled ported Main jet Bc given your drilling skills you probably would have gone through 3 of them before you got it right
can you not just remove the governor arm and spring and by pass the low oil switch and never crack the case open and do exactly the same thing??with much less work ? I understand if your doing a custom build doing all this but if your taking a stock motor and simply by passing the governor can you just disconnect it from the butterfly and and that is it ? also this is the Hemi motor ......do not get me wrong you did a fantastic job with this vid and are doing it all 100% the best way but if a person was lazy can they simply do valve springs and by pass the other stuff?
I remember something about doing something similar on certain year Ford 460 engines that was good for 50 horsepower. After playing with small engines and then air cooled Volkswagens it was amazing how just a few thousands in valve adjustment could effect the engine so I can only imagine changing the valve timing.
If instead of boring that hole through your aircleaner adapter in one size all the way from carb to inlet you had tapered it from about twice that diameter at the inlet to the size needed to match the carburetor you will have a much greater performance gain.
I know this is an old comment but I was thinking the exact same thing, just remove the governor arm and call it done, also just unplug the oil level sensor wire on the outside. Loads of extra non value added steps. We'll not mention the valve clearance on the exhaust port is normally more than the intake as it runs hotter and expands more, so his original clearance was fine.
You should have done a mild port and polish job on the cylinder head ports as long as you had it apart far enough to do it. That alone would make more additional power than any of the other crap work you did. And with taking out the governor and installing heavier valve springs, how much higher is this engine going to rev and still make good power?
He's got a Lathe - But he Does'nt have the proper size wrench to set the Valve Lash.!.!.! I hope that you've got one by now - - - And invest $12 dollars on a Spring Compressor. . . Why did I comment on your Video ? ? ? Because I like you. . . Good Stuff Man
After removing the GOV , I would have installed a billet rod to keep the engine from throwing the stock rod because of to many RPM'S. You can make a spring removal / install tool ( for removing valve springs) from a large C clamp , weld a small piece of tubing on one side of the c clamp but cut out a section for room to insert the small keepers.
Also I recommend a billet flywheel you lose charging is only issue but they make them with the ring gear for electric start I have seen 5 now on mine and others carts explode over 5 grand
what kind of revs will you get after governor removal ? I got a china ( ducar ) copy of this engine .. using it on a longtail.. , would it be possible to just loosen the spring a little bit to get just a little bit more revs, without running into floating valve issues ?
Hi great video!! I need advice.. (Boss has 50+ years mechanic expirence & can't figure out) we have brand new Predator 420cc that we put on a mower. It's putting gas in to the crank case & leaking out the carb when it stops running! We took apart carb made sure it's still nice & clean properly put together etc.. Any suggestions?

Tip: put grease on your tap then it will both lubricate the threads being cut and the grease will hold 99% of the shavings too.
preciate that advice

Again I have no idea why this kid doesn't have more subs, such an engineer giving this vid a heavy like.
OK so I liked it. Been watching a lot of his video and I impressed how much he knows and how well he does it.
Because "drill slightly bigger" isn't a measurement.

"Because... I can". I love that.
So cool ! Can't wait to see how does the engine run !
this channel is so underrated
yes i'm looking for a tool for the valve springs. i am having trouble on my predator 301....great video young man!!!!
Lots of good editing and tricks. Really liked the string at the end.
When tapping the Governor hole put a tac cloth in there and / or hold shot glass under the hole to catch the metal shavings.
Dude there is so much horrifying and terrible info in this video and ur concered about some drill and tap debris? This video i pray is really a joke. Like what not to do to any small motor ever.
Great video sir. Will use this as a reference when I move to a stage two for my 420! Thank you!
Thanks for an informative and nicely produced video. One question, though: couldnt you just replace the spring from the throttle arm to the governor arm to raise the rpm while thus raising the max rpm while keeping the limiter function? Thx.
Thanks for the lesson on how to do this correctly in the process of changing my golf cart to gas engine
Exactly what I was looking for, thanks
Laughed at the painting :D And awesome tip with the spongy rope thingy! I might use that some day
It's called Backer Rod and it is used for backing a gap so you can caulk a joint and not have the caulking fall deep into the gap.
If you’re worried about not being able to get all the backer rod (sponge thingy) out of the cylinder, you can use an air hose fitting to screw it into the spark plug hole and apply 100psi air to hold the valves in place. I’ve done this multiple times when replacing valves springs on Chevy LS motors while it’s still in the truck. This was a great video, and I doubt you’ve put it on a dyno to see the power increase, but do you have any idea how much power increase you got, or how high you can rev the rpm’s?? I know the factory governor had it at 3600 rpm’s.
I thought I was doing good tuning up my GX390 on my pressure washer. You Rock young man . :)
Could fill the cylinder w air through the spark plug hole compressing when removing n installing the valvebsping n valve spring seals . But all in all. Awesome job
Air works ok, if you have a gearbox to stop motor rotating ! ,the soft rope method is very good , but he didnt show winding piston back toward TDC .
I'd definitely use a rope instead of the foam cord. That stuff would be tough to remove if it rips.
again, this kid is great! I like the custom adapter for the air filter. also props to the paint job. that had me laughing! keep up the good work real steel.
he knew what lash caps are.....well done
You can use air pressure to hold the valves back using a compression guage hose & air hose nipple ,Get yourself a round brake anchor pin tool great for doing valves too .
good tip
Those thingies that you're calling "pegs" are studs.
You're welcome.

Good job. Those areas where small parts fall into are called "hell holes"...always plug/cover them before taking stuff apart that could fall in there....I think you figured that out though.
Do they still have small engine class in high school? They did when I was a kid (35 years ago). This kid would be a great teacher for it.

A brass soft plug is my preferred mod for the governor shaft plug.
This video was awesome 👌 no bullshit straight forward good job thank you for making this video
You'll find a nice performance increase by using an offset flywheel key to advance the timing by about 2 to 3 degrees.
I remember something about doing something similar on certain year Ford 460 engines that was good for 50 horsepower. After playing with small engines and then air cooled Volkswagens it was amazing how just a few thousands in valve adjustment could effect the engine so I can only imagine changing the valve timing.
This was fantastic. Do by chance have part numbers for anything?
Good explanation and informative 👍
This is a very informative video awesome job man.
thanks!
thank you for the quality step by step!
Young Master,
Thank you! I have liked and subscribed.
Why not just disconnect the governor linkages and leave it in place? Also, as mentioned elsewhere, oil sensor could just be unplugged.
Or why not just take the governor gear out and leave the linkages so that you wouldn't have to do all that flipping around with the throttle arm
A+. Extremely well done.
You the best paint thrower I ever seen ,,,,,,,damn
excellent presentation. Well done.
your vidios are so good that i can watch them again again again...
That, because I can line is my favorite to use 😂
nice editing on the paint
LotSa Extra steps but really nice job on the adapter.
GET YOURSELF A SPRING COMPRESSOR AND A FLEXIBLE MAGNET
Why open the case to remove the governor sprocket? Why not just remove the arm and spring? Same end result?
Buller...
TheJake In78 that’s what I thought, seems to make no difference
If instead of boring that hole through your aircleaner adapter in one size all the way from carb to inlet you had tapered it from about twice that diameter at the inlet to the size needed to match the carburetor you will have a much greater performance gain.
Great video 😊
I've never thought of inserting lots of small pieces of metal into the carb body?
P.s. good video thx
Tight is right. Too tight is broke!
cant u just remove govenor link on outside of engine,without removing internals?,if it dont close butterfly valve it dont govern it ??

@@robevans8555 You can, but then you run the risk of the governor flying apart in there with the higher rpms. Much better to just remove it.
Not to mention removing the extra unnecessary weight
$12 at Harbor freight. Works great. Less filling. 🏁

Drill the main jet? Even drill marks in the hole you drill effects fuel flow. Always flow test drilled jets.
After removing the GOV , I would have installed a billet rod to keep the engine from throwing the stock rod because of to many RPM'S.
You can make a spring removal / install tool ( for removing valve springs) from a large C clamp , weld a small piece of tubing on one side of the c clamp but cut out a section for room to insert the small keepers.
Can you do a video on that?

@@spinningtireproductions105 ...Yes, billet flywheel also, less rotating mast it will rev faster.
All that work you should have put a bigger cam in and removed the balance shaft !
How big was the hole that you drilled into the main jet? Would help me a ton thank you.
