Mike,

Here are the answers to your questions:

I sprayed starting fluid around the base of the carb after checking and replaceing the cap/rotor/plug wires and was unable to find a vacuum leak.

The vacuum gauge does not jump around at all.

I have done a compression test on 5 and 6 and got 125/135. Should I check some other cylinders? Is that to low?

How do I check for excessive crank case ventilation?

Jumping time would explain a couple of things, but I used a double roller timing chain set so I wouldn't think it is a possibility, should I check my valve timing anyway?

I smells rich at idle, but seems just right on the road. I checked my plugs every day for a while after I rejetted the carb and they looked great. The only change I have made since then is more fuel/air at idle so that my idle smoothed out.

I blocked off the vacuum brakes and rechecked my vacuum, no change.

I am not using any oil at all.

The valve guides where new when I had the heads rebuilt.

It doesn't smoke when started.

Over all I think that the heads are fine, it sounds like I might have some ring issues. Any way other than a compression test to check them?

thanks

schu
