I checked the fuel tank and it's not leaking anywhere. The fuel pressure seems good. I ran it today, I actually got it tuned running good and it was shifting at WOT. then it started running like crap, not shifting and dying at idle after 2-3 seconds. I did notice the needles seem very very sensitive and it's sensitive to fuel level changes. If I tune it and getting it running good at a full tank at 3/4 it will be very lean, especially on the low end and start moving on it's own. I tried the trick of tuning it at a half tank but it would just die after idling 2-3 seconds with a full tank. at empty it would be very lean and start running off. It seems extremely hard to tune because of that and I think that's why I've been having so much trouble. I don't know if that's indicative of an air leak or not. Should I have to remove the body and tune for differing fuel tank levels? That seems kind of a PITA.

Now though at the end of the last run it just started revving up and not moving and upon pinching the fuel lines it revved way up before it died. I checked and it looks like the flywheel moves independent of the clutch bell. Removing the clutch I don't know how to do, I'll have to watch a video on how to do it so I can check.
