Rob Clement - RC Congrads on becoming aflight instructor. I wasn't aware there was such a thing. Does AMA have program set up or was it done on a local club basis?

Barry, MacDaddy since you two are familiar with using 30% nitro fuel. I'm have a heck of a time getting it to run in my older engines (Saito 65, 80), they would not run rich enough to use higher nitro fuel. I could almost take out the high speed needle valve and the still kept running. This being after I took them out of planes, tore carbs apart and made sure they're wern't any blockages and then put them on a test stand. I was using med. fuel line and still no luck. They seemed to get to hot and would not run consistantly. Wanted to get this down before running it in my new 100, 125s. Any ideas?
