is this a new problem that just developed?

Its not the vacuum advance. Simply put....the engine doesnt produce vacuum(or at least much more than maybe 1 inch) at full throttle. So any high rpm, full throttle issues wont be related to vac advance, because vac advance isnt in the mix or doing anything at all under full throttle.

Vac advance only works at idle/part throttle where the engine produces vacuum.

If its a new prob, Id be looking elsewhere



It's like this since the engine was put in the car - they really messed things up and didn't have much of an idea about what they were doing. It gets continually better and better, as the bugs are being fixed, but it still doesn't run even remotely how it should...

So, where we should look? Is it possible that advance is off?

Gettin' old iron accross the pond...
