I have a buddy who has a very original vehicle with a 216. He wants to keep it that way. Someone changed out the carburetor for a Carter with an automatic choke. His, of course calls for a Rochester Model B with manual choke and throttle cables, so we put one on it. I went through it and it was very clean, but I did completely disassemble it, cleaned it in a one gallon can of carburetor cleaner, washed the parts it as hot of water as what comes out of the faucet, blew 3,000 CF or so air though everywhere I could, put in a new leather accelerator pump and new gaskets. I adjusted the float drop and float level.
Here is the current condition.
It runs like a top.
When you shut it off. Fuel vapors bubble out on the left side at the airhorn gasket. The gas evaporates before it runs down the side of the carburetor. The screws are as snug as I dare turn them. While this is going on, there are bubbles percolating in the fuel filter located at the front of the carburetor. The filter is not hot to the touch. Not much more than warm.
Later on, there is a bit of gas showing up at the throttle plate shaft.
I haven't put a gauge on the fuel pump yet to see if the pressure is too high yet (the new metal top pump was put on in 2018).
Here is my plan.
Test the fuel pump pressure. What should the maximum pressure be?
If the pump pressure is within specs, how can I check whether the needle is seating on the seat in the bowl without taking it apart?
What else can I do besides throwing new parts at it?
