I won this engine at a contest this summer and would like to put it on my son's flight streak.
The engine was new in a box and the needle was still in the package. When I tried to screw the needle in it would only go in three turns. I could nto see any reason why it would not screw in. Not crossed threaded. It seemed like the needle was too long. I kept working with it and got it to screw in about 9 turns, but the needle still will not seal off all the way.
The engine will start, run blubbler for about 15 seconds then go lean and shut down. I tighten the backplate bolts about 1/8 of a turn as did two of the head bolts. Still it will not run.
I think I need a new NVA.
Anyone have any clues?
Thanks
Paul
