There is a bolt that can be removed to hold the pushrod up but it really isn't that hard to line the pump arm up with the pushrod and hold it in place. If you do use the bolt method to hold the rod use a soft bolt and just finger tighten it as you don't want to nick the rod and have it bind. When you test a fuel pump the pressure can be ok but you also need to check the volume, I am not sure what the exact volume should be but a good rule of thumb is a pint in 30 seconds.

I also had the fuel line problem as discussed but replacing that did not do much good, neither did the carb overhaul. are there any tricks out there for replacing the fuel pump? don;t some blocks have a tapped hole in the front where you can put a bolt and bottom out against the push rod (holding it in place) thanks for all the advice!!!

The fuel pump diaphragm had a small puncture that released the pressure between the pump and carb. Even the clear fuel filter I use was being drained dry. Dale
