Just came here to say thanks for your video about how to remove & install valve springs without the special too. GOLD I tell ya GOLD!! the other video had comments off.. people give ya crap for using vice grips?? Well they worked PERFECTLY!!

I love it 😍

I recently swapped to a bigger engine on my 20" lawnmower/brush cutter. I spent most of the night and into the afternoon buttoning up the new motor after some slight porting, repaired a cracked intake tube and eyebrow shave. I also ported the head to get more flow around the valves. when putting the valves back in, check the valve lash particularly the intake valve. not sure why the intake lobe on the camshaft has a slight bump that holds the intake valve open on part of the compression stroke. aside from the compression release mechanism on the exhaust lobe, it's also a good idea to check the valve lash on the compression stroke. I usually take close to half a millimeter off the end of the valve stem to get increased compression. turn the flywheel by hand, slowly and observe the action of the intake and exhaust valves. I managed to keep the function of the compression release mechanism this time. I usually shorten the exhaust valve stem 1/2 millimeter to have full compression. I leave the governor off and put a direct throttle control to the carburetor. I only learned of porting and shaving the engine a couple years ago. I've been playing with these small engines for most of my life. they can cut a tree stump if you know what you're doing

a hardcore guy would remove the exhaust threads , good for around half a horse .

If you get orange peel means you need more air pressure less paint. If you get a lot of dry spray then you need more paint and less air pressure. Of course the thin of your paint is also going to be a factor along with what type of reducer that your using.

Exhaust port surface does not matter so much, but to keep it cleaner for longer it does not hurt to polish it.

Intake channel should not be smooth because of the micro turbulence effect. Surface should be ideally golf ball -like, a bit rougher side for the maximal gas flow.

Polishing your intake is counterproductive when you understand fuel atomization.

So I been looking for this kind of info for a long time now on how to do free or cheap mods myself. Great info and one of the best I have seen. Thanks and well done sir.

Great job

you don't want to polish the intake port too much, you want it rough so it makes the air and fuel mix better. if you polish it, it can decrease torque.

That cutting back of the cylinder wall between the valves & the cylinder itself not lower than how high the top ring travels up is called " relieving" & improves the breathing significantly...you even hear it in the Jan & Dean song: " she's ported & relieved & she's stroked & bored" pertaining to the Ford Flathead where they used to put the mercury 3/8"th stroker crank in it & bore & port the block...Jan & Dean wrote most of the Hotrod songs like in American Grafitti but people mistook them for the beach boys...songs like "dead man's curve" etc ...Trev New Zealand 🤗🇳🇿

If you dont have money or cannot find a copper gasket then drink an energy drink. And cut the can and lay it out , trace and cut your gasket.

Looks like a smashed finger,right hand

Very nice young skywalker you got the fundamentals. Now to learn the darkside of force.

I believe that the intake port(s) on an engine are supposed to be rougher in order to mix the air and fuel

Great video Bud!

I was always told, rough intake to help atamiz the fuel?

I think I’m going to check our Husqvarna Intek V-Twin 22 Hp Briggs and Stratton engines push rod clearance as well. It’s never been done and I don’t think the factory did a perfect job on it. Just saying.

Hey so you did good but you should have kept the intake the way it was after rough sand paper but so it would atomize the air and fuel

Little dudes like this are the ones who go Powersports and those guns should be helping out

You need an iwata or sata bro

Damm kid video!

Highly recommend getting a different gun for primer and keeping it separate form yr base n clear gun

Very nice video

Cool cat love your video proud of you

Umm umm good video

💐♥️💐 Thanks for sharing. Plz. Put on gloves to protect your hands from chemicals and dirt. Nowadays, I have a problem running my generator after the lockdown so I try to gain some useful information to repair it, it is not an easy task when you miss the right tools.

What hp is yours?

Good

I stopped watching because although this is an older video, its painful to watch. That piston that's stuck in the port for the choke is the reason your sled is bogging. You don't even know basic components, such as the cdi box, choke assembly. I came here in hopes of viewing images of the carburetor setup for the injector and air box return and all you do is keep talking nonsense. No one cares that you cleaned your garage. No one.

So watched your other video with the four wheelers...runs good now what was it the air flow mixture screw?

A lot of ummm, I hate that but good video stop saying UMMM omg luv the vid though

how you turned it over until the bottom valve stops moving. you'd just turn it again until the top doesn't move??? never done this before. but, this seems easier than a screwdriver in the spark plug hole to find top dead center!

The sign of a young "Manly MAN" and not a "soi boi" @ 3:02. Fingernail dirty and bruised not painted. LOL So nice to see a young MAN, when so many young are "gender confused". You have graduated the school of "Broken Rod's" with flying colors.

Um

U did it wrong . Bottom valve was open.

Maybe need to add my object detecting feature. ruclips.net/video/eDZeLPgYBvg/видео.html

School is the EASIEST thing you will ever have to do in your life!

Thanks, I learned something also, good job.

I hope you make more videos and keep plugging along. Things can be really frustrating, but it makes the final reward all that much sweeter. Experience: It's what you get when you were expecting something else.

I could use this kid right now lol.. Good job buddy you taught an old man something new.. thanks

We saw that middle finger 🤫

What ever happened with the project bro

You're probably not a kid anymore when I comment this but from what you know from this video at your age I know you will go places in life. Great job!

Sounds like a breathing issues take ur air filter off and see if it stays idleing also adjust idle screw

Check out my twin swapped offroad mower! ruclips.net/video/Qr15Odqym3Q/видео.html

Good job kid.

Good job young man, you're gonna be a hell of a mechanic one day....
