I have been working on this thing for 3 days trying to figure out the problem. I wasnt getting fuel at carburetor. I took out both screens in bottom of tanks cleaned them, blew through all the hoses, no resctrictions, replaced the pulse fuel pump and still no fuel. Finally today I figured it out. There is a electric selenoid on the carburetor that opens to let the fuel into the bowl. The hot wire that hooks to the ignition switch to open that selenoid had come loose from the ignition. Just a heads up if you are ever stumped on not getting fuel, another place to look.
