60 lbs of compression is pretty good for one of those. Make sure you oil it heavy, I’d suggest mix at least 8:1. Those motors use plain bearings to support the crankshaft and they are known to wear under the stress of running if they don’t get enough oil. You’re dependent on crankcase compression to accomplish two things here – first is to compress the fuel mix well enough to force it into the combustion chamber, and secondly to also force the fuel mix into the bearings so they get lubed well enough. Have a rag handy to clean up the fuel residue that drips from the carburetor, those things tend to spit out of the mixer quite a bit. The earlier motors with the mixer valve opening completely uncovered were the worst ones.
