120AX woes
I ran my new 120 AX for the first time today. While running a tank on the ground, everything per instructions, it kept quitting like it was eating glow plugs. It was just like hitting the kill switch on a gasser, just off. I ran a few tanks through it, alternating between rich and 10 second peak runs and changed glow plugs a few times (OS#8). It kept quitting like that, but less and less. Finally I took the plane up and just flew around conservatively. It would still quit suddenly every couple of flights. Everything is fine in the tank and it doesn't seem like a fuel thing anyway, in that its just dead, not like when its too lean and you can get off the throttle and keep it running. I finally endind up stuffing the plane when it quit at a really bad time. I've been running OS motors for 30 years and have a ton of them. This is the first time I've had anything like this happen. Am I missing something?

RE: 120AX woes
It was the tank. I replaced it and all plumbing and now it runs great! Funny, it didn't act like that. But oh well, false alarm!
