Hi I have a hard time on this engine I am running 25nitro 18oil enya 5 after a while it going lean it dosent help how much fuel I have in the tank I running some few more klicks then basic on the needles. I have tryed to remove the pump, did try with back plate pressure but it didnt want to start is it possible to fit a oneway valve as the ys engine?'
I know about the new carb but think it is to expensive.
Before it leans out the engine smokes a lot and sound great, right now I am running with throttel curves.
I am open for all suggestions.
