Sounds like water in the gas to me. Or should I say in the carb.s Most of the time it is the cheapest thing and most over looked. I think my fuel tank got some water in it over the winter. Gonna clean tank and start fresh. Also, went out last Monday night to put some boo out and my fuel line cracked right at the tank. Was a pain in the butt. Working on fuel line in the dark and cold, but we got her done.
Not far away. In Bryant if you need some help with it. Tom Booth over there on 165 is very good with them too.
