Just a thought Tim. Is there too much oil in it? otherewise could be worn piston rings maybe.

Could be the rings have got stuck in their grooves.  Standing w/o being started for years or lots of cold running can do that.  
I currently have two engines with that problem, anyone found a good way to unstick them, w/o stripping the pistons out and cleaning the grooves?.

have you oiled the valves? i did that and because they have no valve seals the oil seeps through. the bore could be glazed. my bore was also glazed, after a quick hone and two rallies the smoke has cleared.

as for unsticking without removing the piston rings you can soak in paraffin or similar for a week or so, then using a brass wire brush give them a good clean.
hope this helps,
