filter. The carb was professionally rebuilt about 2000 miles ago, though
it may be in need of adjustment. Anybody have any suggestions on what
might be causing this?

Well, Andy, I see there have been no magical solutions proposed to your power
loss question. I was hoping there would be as I experienced much the same
thing last year -- the engine in the GT6 would pull cleanly (if weakly) up to
about 4500 rpm and then begin to miss and sputter -- lift off on the loud
pedal slightly and it would clean up a little and pull a few more revs and go
back to sputtering.
I was thinking, like Mike, that it was fuel starvation. Or carburation. Or
coil overheating. Or weak valve springs. Certainly, adjusting the fuel
mixture didn't help either way (leaner or richer). Valve clearances set at
10 thou. Fuel pressure was correct. Float level set properly.
I'm hoping changing to the triple Weber setup will improve matters. And an
electric fuel pump. And some larger diameter fuel piping for a little more
volume.
