2 stroke always rich if not reved much? i jetted my cr250 about a month ago and ther plug was nice tan but that was after wot up a hill. now it is a little dark almost black and a little wet around the edge(no where near the electrode) so my Q is will a 2 stroke be rich is not reved much? the last time rode was through the woods behind my house and i was putting and i think the bike got to be completely warmed up but when i was riding up the drive way i nearly stalled it and just rolled the throttle on and wheelied then let it idle for a few seconds but i fighre it wasnt enough to clear the plug. any thoughts? ive never fouled a plug and im no ripper yet. it seems nice and clean through the entire rev range so i dont think its rich. it also dosnt smoke much.any thoughts?
