Just put the new electric fuel pump on the Caterpillar today and it has fuel, it has spark, and it does every thing but start and run. Took out a plug and the plugs aren't wet, but the cylinder looked dry. I know that it is getting fuel to the carburetor. And I know the tractor run previously to the fuel system modification. It was running on April 27 just fine, I had witnesses. I drove it into the shop the next day. I took off the fuel pump, vacuum type, and installed an electric fuel pump on the chassis. I can not get the thing to start if It were life and death. I finally gave up after getting fuel air mixture in the face, don't ask why I stood over the open spark hole and cranked the engine. But I am telling you this so no one else is as stupid as I was today. Now, please help me make this thing start.....

Isn't the factory fuel pump part of the carb?

No, the factory fuel pump that was integrated into the carburetor has been bypassed and no longer exists, and never will again.

Does that carb have an electric shut off?

 How did you do that, looking at the manual it doesn't seem possible.???

Casey I would try another plug even though you just used the tractor  , I would hate to see you beat yourself up and fine out it was a bad plug . Myself I would also give it a small shot of starting fluid . Just to rule out fuel .
