Saga continues.

I have again stripped carbs down.
Using clear tube method, adjusted float level.
Installed 120 main jet, (was factory 110 before).
Still working like crap.Tried to make fuel level even more high, no change.
I've been looking at carb slides, and they move as i rev the engine.

Maybe i have a electric problem?
Onboard voltmeter shows no changes in voltage during reving. 14v.
Maybe I should take up a cheaper hobby. Horse racing for example.

Maybe this will help you diagnose your symptoms....

Basic rule of thumb for 4-1, pods (I realize you're using air box), non stock configuration jetting etc....
