I was wondering if someone could tell me how to adjust carb on the 150 pro v 1988, where do you start, is it one and a hallf turns out from seated or what. I was going to take mine off and clean them an was wondering if someone knew, before i start, they want to bog when you start off, but does good on top end, and you can smell gas sometimmes when your idling. I would appreciate any advise.
