Hey Guys

I need alittle help with a Saito 65. I have several Saitos and have had no problems with them till this one came along. I have had it on 2 different planes with different fuel tanks and tubing. What it is doing is quiting in flight at wide open throttle, It idles fine and the transition from idle is fine. After I dead stick it in I can richen it up by a few clicks then it runs fine for alittle while then quits again. I richen it up more and it runs fine for awhile again. I keep doing this till it is so rich it falles off and I have to go back lean again. Which by now is around 3 turns then it starts all over again. It seems like the High neddle donst make as much difference as it should. I just got it back from Horizon Hobby where they said it was fine. Running 15% nitro have tried up to 30% and an OS-F glow plug still no luck. I few 5 times today and 5 dead sticks.

Thanks for any help you can give me.
