i have a 30mm trenga racing carb. my blaster wont idle when its warmed up. dont kno much on this particular carb but i took the top off and had no idea what i was looking at compared to other carbs ive worked on. also my plug fouls more than it should. i can take it out a couple rides but then i need to change it after that. yall think i jus need it cleaned or rebuilt or whats the deal? also could octane have anything to do with anything cuz i havent been putting premium in jus the low grade.
