ok i got the ivac off so how am i pose to clean it? do u jus take everything apart and clean it with carb cleaner? btw thanks for your help bro

yea just spray it out real good .then let it dry out for a few min. does it look pretty dirty?

it was pretty gunky. i sprayed it really good with carb cleanner. sorry im a newb with 4 strokes i know everything about 2 strokes. results in about a hour. i hope this fixes my problem because i have school in the morning

think that might have been it. so far its been ideling puuuuuuuuurfect for about 5min straight
