school me on squirter cam colors

hi folks,

as i´m going on trying to eleminate some carb misbehaviors (stumbles if i put the pedal down in idle) i wanna change the squirter pump cam.

i bought a set of cams from Quickfuel ... my problem now is:

which color effects what....or is there a ascending order like the white one is the mildest, then comes the blue one etc....

just to get a hint, what will/should happen when i play with the cams

thanks a lot in advance
