Bought this machine new in the fall of 1996. No problems over the years. Only maintenance required has been new bateries, change fluids and belts.

My buddy and I are going through the machine as a result of the engine starting to run rough to the point that it wouldn't start.

Have done the following:
Checked the plug to make sure we are gettig fire there....we are.
Have run the fuel pump diagnostic; 5psi vacuum holds sometime..doesn't other times.
The engine will start sometimes like it has for all these years then others it will not start unless ether is used.

My question is does this sound like a fuel pump problem? Work sometimes then not others.
