Hey, Robert... Last year I came across an OPS 67 that was completely seized. I removed the head and the carb, soaked it gasoline overnight and then I sprayed a ton of WD40 all over it and let sit for a few hours. Eventually I was able to turn the flywheel by hand... At that point I inserted a 1/4" rod shank in the collett and used a drill at low rpm to get it moving a lil faster. In no time, it was turning smooth as can be. Put it back together, and it fired right up. Hopefully your bearings aren't rusted.
