Thanks for the info. I put the cylinder back on and I was surprised how much compression it has with just the top ring on the piston. I haven't had the magneto off yet and it has a fairly good spark. I may be able to use one of my Victa impact starters or perhaps put a pulley on it. I picked up this mower in a group of 3 on eBay but I was really only interested in the Victa Utility model 509 (1963-64). I must say that I am impressed with the design of the Supa Swift chassis which is much better than Victa's of the same period.
