Can you help me diagnose why the engine keeps quitting after 30 seconds or so?
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.
Thanks
