I am trying to get my raider running and it is not starting. I am not getting fuel to the pump. The guy I bought it from said the carb is bad. I tested the vaccum on the fuel pump and it only pulls 4 lbs of vaccum. Is this the normal amount. I would like to get it running before i fork out the money on a weber. Any tricks that you guys know of to get it running if the carb is bad.

You can't tell if the carb is really bad unless you get fuel to it, and you can't get fuel to it with a bad fuel pump. Replace the fuel pump, and the filter, and clean the pickup sock in the tank pickup (like 5 screws on a plate on the front of the tank), then tell us if the carb is bad. Check for a varnishy smell from the fuel in the tank, may well be bad if it's sat for a while.

Set the motor to tdc on #1 plug (pull the dist. cap to check if you are on 4 or 1 tdc) to replace the pump, as it eases the leverage on the pump lever to minimum.

Does anyone know what the vaccum reading on the fuel pump is.

Never seen the spec, but I think yours is lower than I'd want. Test the output regulated pressure and the flow vs. time on the bypass output to really test the pump. THere are two output lines on the pump and one suction line. Find which is the suction by tracing to fuel filter or observing suction while cranking. The other two are outlets, one regulated pressure that goes to the carb, top front center to the fuel bowl, and you install a $15 hdw stove 15+psi pressure gauge on that one. The other one goes to the carb front dside low, to the fuel wells for the accel pump and aux accel pump, flushing fuel thru these and then overflowing to the fuel return to tank hose. You test fuel delivery per unit time on that hose. I'd get the battery charged up hot, and perform a 15 second fuel pump test while cranking. Remember you have a sparking starter and solenoid right below you while cranking, and have an extinguisher handy. Muliply your quantity pumped by 4 to get oz per minute, and you want around 2-3oz/min minimum, if I did the math in my head right, the equivalent of 2-4mpg.

Not exactly sure, but 4psi should be enough. I replaced the suction pump with a push pump near the tank, and it was only 8psi. The carb has a fuel return line, so excess pressure is only going to be used to push extra pressure back to the tank. The stock pump can suffer vapour-lock, and blockage at the filter and in the tank, and checking fuel flow obviously would be a good idea (while cranking the engine).
The pumps aren't commonly a problem, but the carbs often are. I'd get that carb cleaned out and make sure there are no blockages there. If the bowl is full of fuel, your pump is fine.
