How are you leaning it out? Is your '86 WUR adjustable?

Cold pressure settings have little to do with warm/threshold/boost settings. They all need to be set sepparately and then blended to the best compromise.

Your system pressure and cold pressure are both high.

If you have a known working WUR from the '79 then swap them out, check your pressures and be done with it. They all work the same basic way. I've had several WURs on my engine with 3 different part numbers.
