I recently acquired an SP-11. Ran it briefly and she pulls vacuum no problem. No oil shows in the sight tube. I would like to clean it up (inside and out) Any recomendations on cleaning out the old oil? I am thinking of running some diesel fuel init until warms up and then flush it out. Can I pull the head off and clean it that way,, or are there tolerances that I would be messing up?
