When I disconnect the fuel line it picks back up and runs great. I am stumped. Comp. is good, spark it good and I cleaned the carbs. Is this a fuel air ratio thing? If so, how do I fix it?
Thank you for reading this post
Re: I have a 30 hp yam. 1993 It runs rough when the fuel line is attached but
sounds like it could be sucking air. Check the fuel line and bulb make sure there are no cracks or dry rotting. check your fuel tank and pick up as well. When you prime the bulb up does it get firm and stay that way?
