Im running a new puch polini kit with a 4 petal reed, 15.15dellorto and a homoet 4p pipe and was experimenting with jets.
I am mixing rich at 32:1 to break it in and my spark plug is light brown which is usually ideal but since I want to run so rich shouldnt I want my plug to be more black?
Does this mean I should jet larger or should I leave it at this brown color? I am running a 93 at high altitude. Keep in mind this is all brand new equiptment and I do not want to seize.
