Took a vacuum measurement. The gauge says its in the "Late Timing" range. How do I fix that?

Here is a video:

Your engine seems to have a lot of valve lifter noise. IMO I would have Charlie Schwindler check out the fuel pump and get the pressure down and not install a pressure regulator. NAPA sells fuel filters for the glass bowl pump. Ask Charlie to install one. Remove the Carb input valve and clean. Then see if the Carb idle adj screws work and adjust the engine vacuum to the highest and most steady reading. Make sure you change the engine oil. A photo of the engine bay would be nice. You don't seem to have a vacuum leak which would result in a lean fuel mixture. You could remove the Carb top and see how much dirt is in the float bowl. If having the fuel pressure and the Carb input valve clean does not allow the idle mixture screws to adjust correctly then return the Carb to Max after calling him.

Another vacuum chart attached. When you get down to fine tuning best to do one change at a time then regroup. When you get there. New motor to you, it can be a lot of different things compounded. Understand why is important.

Vacuum is low, but that could be as described above.... What kind of cylinder compression are you getting. Keep at it!!!


I believe Charlie is a bit backlogged due to personal life issues. But I believe he also works on 97s. If you are sending him your fuel pump, maybe 2 birds as they say.

Is it better to check compression with the engine warm or does it matter?

Normally checked when warm, ie around running temp. Then if low a bit of oil down the bore and a rechecked to rule out rings perhaps.
