OK, I'm fairly new to the hobby and have an OS .40 FP that has very few hours on it. It ran great for about 30 flights at the end of last year. I fired it up this year and have had nothing but problems. First flight this year went great, no problems. Second flight the engine died in the air, same thing on the next flight. I have had a couple of guys at the field help me, but the problem of the engine quiting keeps coming back.

Engine starts fine, and I can tun it up, then back to idle then back up for a while, then back to idle, then back up and when it gets up to full RPM it just quits. Dead, like someone pulled the plug. Using a good quality 10% fuel left over from last year, and a 10 x 6 prop.

Any advice?
