Back again.
When I first drained the oil, a lot of sand came out with it, so first thing was to drop the oil pan, clean it and reinstall with new gaskets. I left the drain plug out and poured in the gallon of kerosene. A fair bit of crude washed out into the catch pan. I then reinstalled the drain plug and added new SAE 30 oil to spec. Pulled the plugs and cold cranked the engine a couple of times for about 10 seconds each. Reinstalled the plugs and fired it up. The exhaust smoked briefly a bit and then ran clean no problems. Not sure the procedure was technically correct but it worked OK.
