Alot of times that means nothing Sometimes, (most of the time the fuel will leak like that if not all the time) that dosent mean the fuel is getting to where it can be ignited. The fuel has to get between the glow plug and the piston head. In the last two weeks, Ive flown about a little over half a gallon of fuel. I havent had a hard time starting my engine. I just squirt a little fuel in the carb and hit it with the starter and shes a runnin. If its puttering a little, open the needle valve more, probably another turn and a half. Once you get it running, Then lean it out as much as you can then back off just a tad.
