Warrior 350 Which way on the A F mixture screw on the carb to make it run...


Warrior 350 Which way on the A/F mixture screw on the carb to make it run richer? My plug is showing lean I'm only running a K&N air filter NO exhaust stock motor and the plug is still showing lean. I don't get it. Do I really need to re jet the carb just for the air filter?

  • I rode the bike for 10minutes non stop same results on the plug

  • Counter clockwise on your a/f screw. I would count the rotations as u screw it all the way in, (so you know where you started.)Then back it out at least 2 turns and go from there.

  • How long to test ride it to check the plug again?

  • No clue lol. Just back it out 2-2.5 turns and crank it up. Then fine tune it til it sounds good and doesnt bog out when u hit the gas. I just guess at this stuff really. There may be a youtube video that can help more.

  • 150 main is to big....does it sputter at all?

  • No sputter. Bike runs good.was just surprise it's running good until I saw the plug.

  • the fuel screw only controls the pilot circuit only idle to 1/4 throttle nothing more

  • Google plug chop

  • Is ur needle set third from the top?

  • Sorry I don't know just purchased the bike a month ago didn't take apart the carb yet

  • Clean your carb first may find junk in the bowl. Then set mixture screw 3 and 1/2 open you may also have to bring the needle in the slid up one notch also.

  • dont set fuel screws ar 3 1/2 turns out do not go out further then 3 turns out if u need to be 3 turns out then u need a larger pilot jet also like i said earlier the fuel screw only controls idle to 1/4 throttle

  • Have you ever read the performance manual for the warrier .the if not go back to school. I'm an engine builder and you evidently didn't read what is said the carb may need to be cleaned.

  • And the idle mixture screw also controls from idle to midrange and slide needle controls just below mid to high.

  • u need to get a clue i couldnt give 2 shits if u are a engine builder building an engine has nothing to do with tuning one smart guy

  • u need to go do some fucking research on tuning and what circuits control what on these carbs before u start running your mouth and acting like u have a fucking clue

  • Hay I also race and tune professionally why don't you get a clue I've been doing this longer then you've been alive

  • Listen you I professionally build carbs to match an engine you no you aren't even we worth my time you just not worth it

  • u dont tune anything professionally if your running your mouth and saying this bullshit so u need to just shut your mouth go do a little reading on carb tuning and u might learn a few things smart guy cuz it looks like u need it

  • u have no clue how old i amo so dont open your mouth unless u know what your talking about but looks like thats the only thing your good at is saying bull shit that is nothing but bull shit funny

  • Ok asshole I've been doing this for fifty fuckin years you punk ass so fuck u

  • well from hearing your bull shit and bad info and not knowing what circuit seems to do what and where id never listen to a word of what your saying or would let u touch anything i own or advise anyone get anything done from u asshole your the fucking punk keyboard commando running there mouth on facebook that doesent seem to have a clue so just shut the fuck up with your bull shit

  • Ok you so smart how long you been doing this smart ass

  • doesnt matter how long u been doing something as long as u give the correct information u been doing something wrong for 50 years doesnt mean u have a clue or that u have been doing it right if your going to give out any info make fucking sure your going to give out the correct info or just keep your mouth shut

  • i actually work on carbs for guys and am actually working a a set of 660 carbs as we speak heres something to educate u a little bit from your earlier post of going 3 1/2 turns out on the fuel screw u never go past 3 turns out and if u need to means u need a larger pilot jet this is becaust theres a spring that keeps tension on the screw and when u go past 3 turns out theres not enough tension on the screw and it can back out or fall all the way out

  • dont say i never taught your old ass anything lol

  • Its 2.5 turns stock for a/f and get a 147.5 main jet should fix you problem
