I did forget to mention that I have been running amsoil 50:1. We don't have "clean" gas around here and I've used amsoil in other 2-strokes w/o problems. I'll probably mix up a batch of non-synthetic, just to be sure I don't leave any stone unturned. Can you recommend a quality oil?

I was planning on calling BME this week and see if I could get some help. To me the problem seems to random to be mechanical. I was thinking that maybe the ignition module could have a problem. I'll make a few calls this week and see what I can come up with.

Thanks for the suggestions, keep'em coming.
