smokey
I had one several years back that smoked just like it had a bad head gasket took apart found cracked head replaced still smoked after that found the timing advance lever on the side of the pump was stuck and the timeing was not changing properly, I pulled the intake and was able to get the lever on the passanger side of the pump freed up took care of smoking. I have had to adjust the timing on some older engines they would start smoking I just give the pump a little twist to the left smoking goes away, restories some lost power, normally have to R&R pump sometime down the road.
