wisconsin tf engine with lincoln arc welder

My Australian built 20-200amp lincoln lincweld arc welder. Powered by an 18hp twin cylinder wisconsin engine. Impulse magneto for very easy starting. Welds like a charm. Nice smooth welding without sticking. Bought as non runner. Apparently hadn't run for 20-30 years. Not sure if anyone out there has had to take the flywheel off of one of these things but that was a job and a half. Took me three weeks of coming from different angles, heating it, spraying with any lube i could get my hands on, made three different pulling devices. Just did not want to come off but got it in the end. Had to change the points, condenser and re wire magneto, get two broken spark plugs out, clean out two rats nests and fix governor sticking. The petrol tank was rotten and took quite a bit of work to repair. Stunk of stale petrol really bad, took weeks to get rid of the smell, that or i just got used to it! Had to put new fuel pump and glass bowl assembly on. Carby was full of muck. Other than that engine is in remarkable condition for it's age, somewhere around the 1950's. Have been told the machine was ex military.
