Default Re: G16 Carb problems

It doesn't have an adjustment for the high speed circuit. It is a fixed jet.
There are several causes to having to use the choke.
1) High speed jet is clogged
2) Air leak between the carb and engine block
3) leaking air filter box causing lean condition, (Yamaha very picky about this)
4) Carb float set too low in bowl.
