Also worked the carburetor (a 735 CFM Holley 4150).

The carb setup had been dyno’ed, and all the parameters had been optimized for my car.

But it had recently been running rich…. something had changed. It also had a slight bog on acceleration.

I was planning on replacing the power valve, and the accelerator pump diaphragm.

But what I found was that the bowl attachment screws on the primary fuel bowl had worked (slightly) loose. This was allowing fuel to bypass the metering in the metering block, and causing the rich condition.

Happy to get that issue worked out, a no-cost solution!
