:tire: i have a used revo 2.5 it runs at idel or a little above idel but spits a mist of fuel out of the carb when engine is runnining and only runs for 2-4 minutes i can pull the muffler pipe off and it has a build up of fuel in it enought to drain some out. i even tried to cut the fuel flow adjustment way down like just enough to run engine and got the low air speed set at best to run a little pass idel. is it the carb or engine the problem.?? :flaming:

first off you shouldnt run your motor with out the filter or it will be shot and at idel you will get a little access fuel in your pipe id put the needels to factory settings and then see how it runs you might have your idel a little high also

Are you burning a whole tank of fuel in 2-4min? If its idling and quits after 2-4min, its loading up cause its prob rich. Set needles back to factory and tune it from there. HSN 1st, then LSN, and then set the idle.
