Did some more playing around today.

I suspect that the engine is not getting enough fuel at the top end, and not overheating.
Previously, I could get some good RPM numbers but they wouldn't hold. Idle was good , up to half/three-qurter throttle was good, after that was inconsistent. Today was the same, then I tried playing around with the choke(which I still have on) and got nice consistant high-end, although a 100-200rpm less than with no choke.

So, first of all, would you guys agree with my assesment?
Second, if you do,how best to richen the top-end without ruining the idle/mid-range?

Drill out the main jet?
Try to get to the high end needle?

any and all suggestions are welcome.
