I went for another test run, hoping it had cured itself, but no.
A day or two earlier, I was revving it as hard as I could in third, to see how many revs I was short of in top, which in top gear result in only 45 mph.
The next day, the engine sounds flat, and if I'm lucky i make it to 40 mph, which it won't hold on to.
I have tried a complete different dizzy, carb bowl, checked the butterfly and choke, changed the plugs.
Brakes are free.
All compressions the same at 100.
I suspect I have taken the edges off the top rings.
Any other ideas? I can't drive around at 30 - 35 for long.
