OK, I hooked up the carb as you guys mentioned. And I tried to run the engine. When I tried to choke it to get fuel to the carb, I noticed that the fuel wasn't getting all the way to the carb. I put a starter to the nose cone and the the fuel in the line never moved. The engine has good compression. I tried blowing on the vent line of the fuel tank to see if I could get some fuel to the carb and it wouldn't move. It's as if the carb is plugged. So I took the carb covers off and verified that the gaskets are OK, and the diaphram and spring are OK. Any ideas?
