All,

First, deepest gratitudes to those of you who have offered advice thus far.

I disconnected the fuel lines and tried the container method.  Fuel line In
comes from a jerry can; Fuel Line out goes to an empty bucket.  I turned
over the engine a few times hoping to start the priming process, but the
fuel bowl never filled and the bucket is as dry as the desert.  

Well, we do have some humidity here in North Carolina, but let's just say
there was no gas in the bucket.

I'm assuming then that the obvious possibilities are that the pump is bad or
the cam shaft/push rod is damaged.

Now for a bit of history.  I tried replacing the fuel pump some time ago,
ran into this problem and returned the mechanical pump.  Bought an electric.

Let's just say I never got the electric working.

I ordered another fuel pump (the current one) to install.  Same issues as
last time.

I'm going to try to pull off this pump and give it the vise treatment to
make sure it actually pumps.  I'll send a follow up note when I've tested
the pump.

For the record, it's a Master (Carter) model 1117.  Don't know if that means
anything to you guys, but thought you might want to know.

Thanks again!

Assuming that gas can get from the tank to the pump(i.e. gas was flowing
fine before the previous fuel pump died).....

There is little you can screw up on the install. If inserted straight and
bolted flat to the mounting boss, the fuel pump arm doesn't really have any
place to go except up against the eccentric on the camshaft nose. The fuel
pump is prolly either DOA or(as you suspected) the wrong one. Compare the
operating arm with your old one if you kept it. You can test the pump a
couple of ways. Disconnect the line to the carb and stick it in a container,
then crank the engine. You should get plenty of gas in the container fairly
quickly. Or, with the pump off the engine(in a vise with soft jaws is
easiest), stroke the operating arm. The pump should make decent suction on
the inlet and have an obvious output 'puff' of air. It's pretty easy to spot
a dead one this way FWIW, it's a positive displacement pump that needs to be
able to self-prime.

If I suspect a gas flow problem to the pump, I hook up the hand vacuum pump
and brake bleeder jar to the tank line out and see if I can pull gas into
the jar.
