Just statrted my fl 70. Richened the aribleed and runs great. But now the engine is squicking and kills itself instantly at idol. I started it up again but the problem got worse and the squicking was very loud. I killed the engine on my transmitter in fear of something bad happening to it. What the heak is it. Anyideas. I guy at my field said you have to maintain the valves every 20 flights. Could this be the problem. I have one flight on it and have run the engine at least 15 times breaking it in and trying to get it running right.
Thanks
