Gas Pilot Light Valve Not Opening
I have an older gas furnace with electric ignition. The pilot light wouldn't light. It will try for couple minutes then turn off, but will never light. My first feeling was that it was the gas valve. I bought a brand new valve and installed it. It worked once to fire up and then stopped. It seems like I am not getting gas out of the pilot valve.
My question is what power is supplied to the gas valve to let it know to open up the pilot light valve. There is only two wires running to the gas valve.

It's more likely the pilot orifice is clogged.
A gas valve that operates a spark lighted pilot light needs three wires.... pilot valve, main valve and common.

I just took the burners out and cleaned the pilot orifice and blew it out with a air compressor. If I disconnect the pilot tube I don't feel or smell any gas coming out. The furnace is a RUDD and the valve is White Rodgers 36c. I attached a couple pictures.
Could it have anything to do with the pilot adjustment screw?

Ruud is a start but they made many furnaces. Look for an ID tag on side wall near the burner.
That covers dozens of valves/options. With this type of equipment we're dealing with we need complete model numbers.
