Fellas - Finishing up the build on an 020T Super. Rebuilt the Walbro carb. New rings. New fuel lines and fuel filter. Did not split the case and did not change crank seals. Running fresh pre-mix fuel. Had points ignition with weak spark so swapped to electronic from a parts saw. Set flywheel gap at a thin business card. About the only thing that is sub-optimal is the spark plug wire; it's a bit sketchy, but no bare wire showing.
It tuned fine on the low speed jet - idles at 2,800 but when I went to tune the high it was surging at high rpm - basically from about 8,000 - 14,000.
That's a new one for me. Any ideas? I do have a spare carb that I can rebuild and swap on.
Thanks
