Thank you guys for the advice, I'm still working at it. I definitely bit of more than I could handle. I feel pretty good about the timing as I've checked it several times and it seems dead on. I'm going to check the valves and possibly pull and replace them.
Im caught in a catch 22 now, a mechanic said he was going to charge $40 an hour and had to find the problem whereas finding this extra longcase 50 is nearly impossible. Thanks again for the info and I'll keep you updated.
