i have a warrior 350 and it has been sitting for a while under a shed. i bought a thumb-throttle for it because it had a twist throttle that i hated. i installed the thumb throttle several months ago. i have started working on it this last week and it will not hit any thing past half throttle. i cleaned the carb and the boost injector pin? (its supposed to compensate for sudden WOT?) or some pin in the bottom (I think) of the carb was not moving as it should so i turned the spring around and it worked better. i am wondering if i have overlooked anything simple? do i just need to clean the carb again?

the only time i can get it to rev really high is when i spray some carbcleaner into the intake, then it will rev way up, other than that you can go about half throttle.
i really cant wait to hop on it and take it out riding but its not fun to barely be able to hit the gas. so if any of you expert gurus have any ideas id love to hear them, thanks guys

Yup, i'd clean the carb again. Maybe soak it a bit.

 

said it before, say it again, check the parking brake cable unless you already fixed and disconnected that...lol

it could be a bad fuel filter, not enough fuel is being let through the filter anymore, i'd say air filter, but you have that off if your spraying cleaner into it while its running.

 

is it possible that the main jet is clogged? or a whatever jet that is used at WOT?
