Just to add the final chapter to this book, I put everything back in the airplane, EXACTLY as it came out. Same lines, fuel tank, nothing different. Took it out today and it started right up. Still not sure exactly what the problem was, I've had guys tell me that they never run their gas engines out of fuel and they've never had a problem similar to mine. For some unknown reason, I could not get the gas to flow into the carb, and that's why it wouldn't start. Once I got the gas to flow, no problems with starting.

FWIW, the carb and all the lines are exactly as it came from Brillelli. If any changes were made, it was made by them. All I did was hook up the feed line and the line I've been calling the static pressure line that runs into my engine box.

Doesn't matter, it's running now.

Thanks for all the help and suggestions.
