Larry, if it starts stumbling after a run at speed, but starts running fine
after a few minutes at idle, it almost sounds like the fuel pump isn't
keeping up with the carb's consumption of fuel (i.e. it can keep up at
idle, but at speed it just cant keep enough flow up).
Another possibility is that your coil is on the fine edge of flaking out.
Just some ideas to think about. This may be a tough one to diagnose.
