Redneck Posted May 21, 2012 Share #14 Posted May 21, 2012 (edited) What you are describing in not starving for fuel. If it is starving for fuel at cruise speed then when you throttle it it would just bog down and quit pulling. With a fuel starvation problem the more throttle the worse it will be. What you are describing is more like a flooding problem open throttle is more air to burn more fuel less throttle is less air. It sounds like you have a carb flooding not starving.

kwisor Posted May 21, 2012 Author Share #15 Posted May 21, 2012 hello if i have a flooding problem what steps do i need to do to correct it? bumble bee Link to comment Share on other sites More sharing options...
Redneck Posted May 21, 2012 Share #16 Posted May 21, 2012 There are a number of things that can cause what you are describing ranging from debris in a needle valve bad fuel water in fuel pluged circuits in the carbs ect. What I would do first is drain the carbs ( screw on the side of each carb at the bottom) open the drains a couple of turns and catch the fuel so you can check for water debris ect. With the carbs empty and the drains open turn on the key and let the fuel pump flush the carbs. A dose of sea foam or b12 may also help. Link to comment Share on other sites More sharing options...
Condor Posted May 21, 2012 Share #17 Posted May 21, 2012 Sounds to me like you have a couple of dirty plugs. Toss in another set and then tell us how it's running. Sea Foam will foul spark plugs.... Link to comment Share on other sites More sharing options...
