fuel not getting through the carb...

Hi all,
I'm having fuel starvation problems.... I can't get the old girl started, as I'm not getting fuel to the combustion chambers. The electric fuel pump works fine. I've replaced the fuel line, cleaned both the racor and polishing filters, permatexed the fittings, cleaned the carb, replaced the float valve and the floats, replaced the carb gaskets... I have a new priming bulb, which is rock hard once fully primed.... still no fuel to the chambers.... I've got good compression, good spark....

The only things left to check, it seems, is the oil pressure safety switch and the manifold gasket...

Any hints from the learned panel?

Does the electric fuel pump "click"?
Go ahead and bypass the oil safety switch to check it.
If you disconnect the fuel line downstream of the fuel pump is there flow?

Jerry,
Should I bypass the oil pressure safety switch by attaching a wire to its positive lead and attaching that to the positive lead of the fuel pump?

Jumper the two terminals on the switch to bypass it. Can you confirm fuel in the carburetor bowl?

Neil,
There has been fuel in the carb bowl when I've taken the carb apart to clean it. Not a lot.... but a few tablespoons comes pouring out of the carb...

I'm wondering how the fuel got into the carb bowl, fuel pump or squeezie bulb? How did you determine the fuel pump was working properly? Jerry's oil pressure switch bypass should help answer that question.

With fuel in the bowl I also wonder about the status of the choke.
