Default Re: Air mixture screw thingy... I think

#2. My engine starts to make a bbbbbbbbbbbbbbb (not smooth) noise at certain throttle positions. When I twist it some more, it sounds like, mmmmmmmmmm (smooth). What could be going on with the engine? I asked my dad and he said that it is because the engine is out of balance... is this true. If so, how do I fix it?
1) Makes sense - because that is your idle screw.
2) Allow it to break in and then start adjusting stuff per all the threads here. (Not a matter or turning screws unfortunately)
