I'd check the piston and bore. You can look into the intake and exhaust ports. Isn't the oil controlled by the throttle position? Hold it WOT and kick to get oil up to the intake boot.
I had a 1979 when I was a kid.
Yep, ran it off and on for two days with no oil in the mix. The oil injection pump is indeed controlled by the throttle position. The throttle cable has a Y adapter near the gas tank and one cable goes to carb and one to the injection pump.
I have been kicking it and holding the throttle open but the oil seems to move incredibly slowly. I guess that makes some sense if it's supposed to be pumping roughly 1/30th - 1/50th as fast as the gas?
