Has anybody figured out why the Moki 2.1 has a fuel draw problem and what causes it? About half the folks I talked to went to the Cline regulator to fix the problem while about as many say they fiixed the problem with oversize fuel line between tank and carb inlet. I decided to go the cheaper route on mine and try the oversize fuel line (large) and drilled out the tank pickup clunk to match. Engine seems to run fine on the ground during breakin but we shall soon see what happens in the air. My curiosity comes from the fact that these engines can be run blubbering rich with medium fuel line while on the ground , which logically tells me that the fuel line diameter is adequate. This fuel line thing just doesn't make a whole lot of sense to me, can anybody shed some light on this subject?
