If the walls of the cylinder are completely rusted, use a flex hone first to knock off the rust then beat them out, also what model of contiental is this, most all of the older ones were wet sleeved engines.

    Kevin,
    I am not familiar with this technique. How is it done with a propane torch?
    Thanks,
    Nick

      heat the walls not the oil.

      Simply fill the cylinder, heat the walls of the cylinder, oil will smoke, no need to stick the flame on the oil, it will not burn right away, trick is to expand the cylinder walls, while keeping piston slightly cooler, the heated oil will wick its way into the rings and down the cylinder. If cylinder walls are heavily rusted i would run a bead hone to knock it off before turning the engine over, heavily rusted walls will likely stop at the first or second ring, very easy for a stuck ring to break when it hits the rust wall. Cylinder will need to be cleaned with soap and water. Must be clean or the abrasives from the bead home will ruin the cylinder walls fast. Once free work the hone to elimate the rust from the cylinder. If all else fails get a large wooden cylinder slightly smaller then the engine bore and smack each piston, normally at this point the engine needs rebuilding,

        Bob, have you tried filling the cylinders with white vinegar and letting it sit a few days? Vinegar will eat rust pretty good.

          I have not tried the white vinegar thing.
          I'll try that next.

              If you were closer to me I'd buy your SA-200.

                I think the guy drove from Iowa to get the last one. I should and could have got 500 more for it but it moved in a flash and had very few hrs on it. The one I have now has had a hew engine in it I believe. The hood is a replacement but all the workmanship is very good. I cleaned the fuel tank and added a shut off.

                  If you have the head off pour them standing full over the top of the piston and give them a love tap a couple of times a day.
