The latest.... My engine builder took my engine and now won't return my calls. He has had it for almost 2 months. His helper called me and said that he was told the problem was due to fuel dumping into the engine and washing out the oil. I'm not sure I believe this because the carb was running very nice and there was never any smell of gasoline. Also, the fuel filter was taken out and there was no sign of fuel there either. My guess is that something wasn't done right in the engine originally and is now being covered up by saying it was the carb. This total nightmare just won't end.
