Having major issues with my tower hobbies .46 glow engine. The thing dies on me as soon as I remove the glow starter. I can't seem to get the needle valve setting right. I tried just about every possible combination. It is so frustrating. On top of that. I just sent back my OS 46AX engine because it was having the same problem. I'm screwed. I hope they send me a new engine. I'm determined to get the tower hobbies engine running. Today I will mess around with it some more.
