Small Engine Carburetor Jetting Basics.

Today i got a short and basic video on understanding jetting, pilot and main jets and when and why to change them.

I remember as a kid I’d always just drill a bigger hole in my jet instead of buying new ones just to get a lil more power out of my go kart

[zakstahl]

Ive solved alot of my problems with a racing spark plug it may not fix yours but every time ive ever put bigger carb on small engine and it got to much gas either.idle or top end racing plug helped me and others more often than not thank for video your simple explanation was good

“I don’t know how the fuck you say that” 🤣 You got my like and subscribe ASAP😂😂💯

Very good informal video! You prolly should do one about how to tell if you're rich or lean by looking at the plug.

Bro thank you for this video! I’ve been tryna find out how these carbs work

So question, help me out here. I just picked up the predator 459cc motor. We are allowed to run a aftermarket pipe and air filter assembly. I will be adding a spacer between carburetor and block for a pulse fitting. Have to leave governor on and cannot exceed 3650 max. Should I do anything jet wise to the carburetor?? Thanks..
This is for a racing lawn mower.

20% of what! Damn it! More explanation please 😊

Is the mixture screw under that little plug.

I still dont know what changing the size of the emulsion tube does to the performance of the engine like how you explained with the main jet has an effect from qtr to half throttle.

[jonathanwillis]

I put jet A that came with my 224 but it wants to kill when I reach high rpm’s do I try jet B or C?

[sawyerbennett]

Don't replace the jet just drill them one size and try it then if it is still lean go with the next size up

Good video. This helped a lot. I bought a upgrade kit off ebay valve springs, intake kit, exhuast and jets. Im at a .038 main jet right now. After I hit the gas it won't go top speed. Just cuts in and out. Then shuts off if I stay on it. Any help would be nice.

Hello from the high desert( 6000 ) of New Mexico USA 🇺🇸. What size main jet would you recommend for a Predator 3500 inverter generator, I have a number 68 in it now and it still surges up and down. Keep up the good work and stay safe

[raasch]

I have performance exhaust and intake installed and I just jumped from the stock .028 to a .038 jet on my predator 212. It runs great at idle and with a little gas but at anything higher than that it sputters and falls on its face. Do I need to buy a smaller jet or is there something I can adjust on the carb itself.my float bowl is also leaking fuel even when the engine is off. Any thoughts on what I should do? Thanks

[Hiee]

what would be the biggest jet I could get for a stock air filter and removed governor? with out it running rich?

[SoLoCruizer]

just subbed to your vids hey i have a ducar 212 and i put the stage one with 38 jet i dont think it likes it because i cant run it without choke yet brand new motor only ran 20mins in total just on choke

[Partnerthedog]

This biggest thing you forgot is how can we tell if its running lean or rich, im at altitude so this is tough for me. About 6000 elevation

[jerrystatic]

My bike idles extremely high after startup. The idle screw makes no difference. Should I go up or down on the pilot jet?

[lilkanethebig]

I just bought the Predator 224 Max Output engine. I'm wondering.. can i use the biggest jet (jet c) that comes with with the bone stock engine, or do i need others mods or any other tuning on the engine before adding the biggest jet they gave me?

[Deucealive]

What size pilot jet do you usually run? I think the stock size is around .016". I may open mine up a bit because the off idle is not as good as it could be.

What I don't like about the Huayi carbs is I'm not sure where to get the low speed jets. If I had to buy a carb I would get the RuiXing carb from ARC racing. They also have all the low speed jets for it. Supposed to be one of the best stock carbs you could get under $20. Their low speed jets will not fit the Huayi.
