Not sure how you measured compression but those numbers are extremely low. Did you have the throttle all the way open? The Factory Service Manual has specs like 190 psi with a 170 psi service point.  I've had several motors that run fine at around 130-140 psi. That could be a problem.

Could be a fuel pump issue.  They are known to go bad.  I had to replace my fuel pump last year.  Also, look for cracked/loose vacuum lines

A lot of times when the fuel pump goes, it leaks oil out of the weep hole in the pump.  That's a telltale sign.
