Motorcycle Repair: Air Gas Mix, 2 extremes, minute intervals


Question
Sorry, I meant the choke, not the clutch. Its a semi manual bike. No clutch, but I have to shif gears with my foot. Kinda like a trike (Three wheeler).

Hi, I has a 4 stroke 110cc dirt bike. I played around with the idle and now I'm in trouble. The bike will only idle with the clutch on. When I take the clutch off, it dies out. I am no pro with bikes. I may even be naming the part that I screwed with around with wrong. It's was a small screw with spring (Flat Head Screwdriver) next to the clutch that I turned clockwise and counter clockwise. When I turn this screw the bike revs up. If I turn it the other way, the bike dies out. What do I do to get the bike back to normal where it will idle with the clutch off?
-----Answer-----
I don't understand what the clutch and the carb have 2 do with each other.  Will the bike idle in neutral?  If so then u r fine.  Does this bike require u to pull in a clutch to shift?  If so then when u let out on the clutch it is engaging the bike 2 go.  Therefor u need 2 give it gas 2.

Answer
Ok, was the spring on the screw visible or did u find the spring when u took out the screw.  In any matter u need to set it back to where the bike will idle on it's own, wait 5 mins, then adjust again.  All adjustments should be small or short turns and in 3-5 minute intervals as the vaccum has to catch up and level off.  Twisting in large turns and very quickly will only get u 2 extremes as u've already found out.
