Re: Proper psi at carburator

With all that replaced, does sound as if the carb is a likely place to start.

If that checks out, specs on the 52 & 53 mechanical pump capacity are 1 pint in 45 seconds @ 4 to 5 psi, 1 1/2 pts on the 54s. No RPM mentioned those years but 500 RPM on the 55s so probably at idle speed. If the electric pump can't do considerably more than that just turning it on, then something is sure clogged so at least a place to start looking.
