Hey, I don't know if this was intended for me. My engine is on a stand in the garage awaiting its new oil pan gasket. Hard to try anything out or get more data. I was changing jet between coats of paint.
The PV should be less than half the vacuum at cruising. I tried 10.5 at one point because the vacuum was around 22, but that didn't seem to help anything. I couldn't find my 8.5, think I have it to somebody. 6.5 was what the carb came with. Found what I had written down in my log didn't match the jets. Need to get this all back together and running so I can get back to the ignition. If like to try having that trimmed, but don't want to do it before I try these things out.
