Today a few seconds after starting my plane, the engine mysteriously stopped, for no discernable reason. After turning on the fuel pump (I normally start without the fuel pump on) and restarting, everything was fine. All engine instruments reading normal. I taxied arouund for a while, did a runup, no problems. Flight was uneventful.
What could explain this? With almost 100hrs hobbs time, this has never happened. I have a carbeureted o-320 with one elec ign and one mag. The fuel selector was on (left tank) and both tanks had fuel. As I said, after turning on the fuel pump for the second start, the problem did not recur.
One thing I did notice, is later after the flight I was inspecting my left tank vent line and found wet fuel around a vent line fitting on the right tank. I removed the line from the fitting and inspected the flare, which was fine. I did have some fuel dribble out of the vent line when i removed it from the fitting, however. Not sure how it got in there.
Any theories as to what could cause an engine to spontaneously stop just after startup, and then run fine? It had sat for one week, and it was not very cold out, and I did give it a good dose of priming. I started without the boost pump on, but I routinely do this and have never had a problem.
