Glen, When my engine is cold, it will stop running shortly after starting unless i keep priming it until it warms up. Then it runs great. I am concerned that you only put 2 quarts in the fuselage tank, that is not enough. I would put more fuel in the fuselage tank and after starting keep priming it and see if it continues to run. If so, you may have solve your problem. All the other suggestions are good ones to do also. Lee

Please review the sequence of events and offer your thoughts:Aircraft was found to have excessive water contamination due to sitting outside with cracked fuel cap gaskets. All three tanks were drained completely. 2. Because one of the main tanks had some weeping through the rivets, we removed the tank and sloshed it with a Flame Master product. After 4 days of curing, the tank was reinstalled. About 2 quarts of fuel were put into the header and 5 gallons into the mains. 4. Engine was started with one shot of prime but only ran for a few seconds. 5. Engine was restarted several times but only ran for a maximum of 30-45 seconds before stopping. Various attempts were made to adjust the mixture from within the cockpit and also to use the accelerator on the carb (via the throttle) but the engine ran rough and eventually cut off within 30-45 seconds.6. If the engine was allowed to sit turned off for 1 or 2 minutes, it would restart and run for the 30-45 second interval. 7. Aircraft allowed to remain tied down over night.8. The next morning the engine started with one shot of prime. The engine continued to run smoothly for over 5 minutes at various power settings. That is, it appears that the engine is running OK. Before taking the aircraft for a flight, I would like to have a better idea as to what might have happened to cause this problem. Please note that the aircraft was completely drained of fuel, including the carburetor, for approximately 8-10 days.
