My setup is:
Standard 50cc Cylinder
Tecnigas Enox
Polini Reeds
Spark Plug - B9ES
Polini CP 19mm Carb
I have fitted the new carb and got the bike running pretty good but when I checked the spark plug it is white.
Should I be using a B8ES spark plug instead of a B9ES?

Re: Spark Plug White
Maybe you can try a little higher main jet in the carburator.
Mostly white spark plug means the engine isn't getting anough fuel.

Re: Spark Plug White
I have tried going up on the main jet but it makes the bike run a lot worse

Re: Spark Plug White
Then put it back, the color of the spark plug is just an indicator, but it's not always right. Could you post a pic of the spark plug?
