I like that even after all these years, I’m still learning stuff.
I had it in my head that I’d just spend the money and order a high volume oil pump. I’ve never paid much attention to these other than to pack them with assembly lube to prime them before a fresh fire and to dissect them after a tear down. I knew nothing of the importance of the spring inside. Seeing Nick add a thin washer between the spring and the bolt was an eye opener. Dwayne Porter suggested the spring change.
I grabbed my old HV pump from the scrap pile.

The 15/16" bolt comes off.

Is it really as simple as this little spring?

Access with the pump in the car isn't bad. A Stubby 15/16" wrench fit in there. Quickie job.
Cold fast idle....just shy of 74 PSI.

Next up, I adjusted the rear float. The booklet that came with the carb stated that after adjustment..... to lower the fuel level, the fuel needs to be used up. Instead of that, I backed out a bowl screw and let some gas drain into a towel. I'll go for a drive soon and see how the change affects the stalling issue.
