dalolyn, You are right that with 1/4 to 1/8 tank you should have a fairly stable fuel supply unless you flip it. My comments are based on just before the tank runs dry so you can get out of the throttle and not have a lean run under load as it quits running.

46u, that is exactly what I was thinking about. Now I know where to get one and I can stop carrying a rag in my pocket when I turn marshall 1/8 scales and they are broke.
