The only way I can get it to start is by squirting premix into the carbs and then it starts fine. If I shut it off and let it sit longer than 5 minutes it won't start back up with out squirting it again. I replace fuel lines and clamps except for the really small ones on the carb, they appeared ok with no leaks. The motor runs great except for the starting problem, idles normal. I believe it is around a 1987-88. Any suggestions would be greatly appreciated, Thanks.
