Not getting fuel... big issuse!

The pump has an arm (like a lever) that works against a fairly stiff internal spring. If you hold the pump tightly in one hand, you can barely work the arm manually. If you can, you will hear the diaphragm "pumping" air each time you work the arm.

On the cam shaft is an eccentric lobe that the pump's arm sits ON TOP of. If you accidentally installed the pump with the arm UNDER the lobe, it can't pump fuel (the arm won't go up and down).

The comment about a "wire on the eccentric" means that you can use a stiff piece of wire (coat hanger) and reach inside the hole in the block where the pump mounts. Rest the wire ON TOP of the eccentric lobe and bump the engine a few times to notice what happens to the wire. It should ride up and down in your hand. When you feel like the lobe is at the bottom of its stroke, install the pump, making sure the arm goes on TOP, not UNDER the lobe. Then, give it a go...

If you want to try the gas-down-the-carb method, it doesn't take much. If the pump did work and you watched what happens when you press the accelerator pedal, you would see a shot of fuel probably less than a teaspoon spray into the carb's throat. Dump it straight down the throat. Or... get a can of starter fluid (ether) and give it a good spray down the top.
