Pilot jet controls...

[masterblaster81]

On the stock blasty mikuni carb, the pilot jet controls:
a. air - bigger jet = leaner mixture
b. fuel - bigger jet = richer mixture
c. I have know idea

anyone know? i don't..... its not a test but more like a group brainstorming activity

If you upgrade the main jet pretty high like 320 would you need to up the pilot too? what would be a good size with a high main jet like that
