Thanks guys for all the input.
After changing diaphragms in the regulator on the bottom of the pump and the regulator by the carburetor and playing with springs and testing all that I can – nothing seemed to change.
However, once the ambient temperature changed from the 60s to the 80s, the fuel pump would spike to 11 and then settled to six more quickly as to avoid bending the float tabs and flooding the motor.
Several years ago, Mallory tech was very hard to access and Mallory was then bought out by MSD to which now has been bought out by Holley and there is no tech support for this pump – you can just buy a new one if you want.
Decision: is to run it and see what happens.
Thanks for all you guys help – take good care, Craig
