What have you done today with your Austin Seven
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.
