Are the vacuum hoses nice and tight and not spongy.

Correct me if I'm wrong, but I thought that engine didn't have a pump? Did you get a different pump from a 31000 series or ???
I'd definitely get fresh gas. If nothing else, it eliminates that as a problem. You'd hate to start clogging up a new carb & filters.

Whar was the problem that kept it fron starting?

i put 12 volts to the kill wire bubbled the coil i got a
new coil today and it started right up when it starts to die i place my hand over the carb and it pulls out of it so i suspect bad fue the carb has only one adjusting screw and that has a limiter on it the vaccume port is on the the intake manifold i hope i have the wires hooked up right i left the kill wire off since when the key is turned off the anti-backfire solinoid shuts off the motor

And the fuel pump is from?

it is a 3 line vaccume operated one that i bought it is a brigg's plastic pump 1 vaccume 1 to tank 1 to carb.

Hope everything works out.

I'd mentioned too soft a vacuum line. IF the line is too soft, it will flex and "absorb" the vacuum "pulses". Also, don't make it any longer than necessary.
