Guys,
ive tried bumping #1 multiple times while the pump is running in the test pump mode to no avail. If I do the prime function and bump it multiple times it works as stated above.

Dantley, my understanding of the G3 differences, which is very limited, is the auto relight feature. I was test running the engine yesterday and powered up to taxi (after I had been taxiing a while) and it started hesitating badly. Imagine my surprise when I walked up to it and realized it was running out of fuel and continually relighting!

I have this engine in a a PNP F-16. It fits fine and looks great. I used one of the two smoke tanks for fuel and left the other one smoke. I will let you know what I find for flight times, but I'm anticipating 7 min at reasonable throttle settings
