Re: frustrated
Well here is my two pennyworth. Dont run with suspect carbs. You will burn the motor up. Take the carbs off and use the Carb cleaner kit made by the manufacturers of Gunk products. Just a few bucks from Advance Auto. Strip the carbs soak them and the jets good. Follow the directions on the can. Do not use this so called, Spray type, carb cleaner. It will do damage.
Use new gaskets and you will get a good job. Even if there is no sign of build up in the float bowls the little drillings and jets can still be blocked. When you have finished use Stabil in your fuel and forget about carb's for a while.
