hi,
I have one in running condition not restored. mine has two taps left side of sump, I presumed these were upper and lower oil levels and this has worked so far. oil gauge missing on mine, put a tap there instead and open it to show oil flow when running. mine running with impulse mag off Hercules? engine off sunshine baler. don't have to crank it, only pull it over compression. have wrong carby, shebler economizer I think it is called? turn fuel on and choke on , three or four turns over compression and it will fire. if you strong enough to crank it with non impulse magneto I suggest full retard . from memory, I think governor takes care of throttle.
