actually, mine does that too. after a flight, if there is still tank pressure, fuel will dribble out of the carb. as soon as i pull the plug it will stop. i don't think that's really true. it may be true on paper, but in the working model, i don't think it works as well as expected. i've got a question for you guys. i was at the flying field on saturday, flying my cap with my new 110. it idled fine that morning, and it was a very foggy. the fog cleared and the idle got messed up. what's puzzling me is that it idles at 2000 within a hundred rpm. it idles great, and then it seems to simply stop firing. it doesn't bog down and stop, nor does it speed up and die. it just stops. this is only at idle mind you. usually it will idle about 30 seconds before it does this but sometimes it will happen almost immediatly after idling down. that is fairly rare, but it makes me nervous. Do any of you ys pros have any ideas?
