235 Center of gravity

[Jemezcrusher]

I have my 235 on an engine stand. Had difficulty getting the arms on the stand to connect to upper and lower bell housing holes but finally got it configured.

I am going to make some shorter arms as it appears that the engine (standing straight up) is above the center of gravity. The center of the pivot is closer to the crank than the head.

Anyone got a good idea where the rotating axis should be so that it does not flop over when I start to rotate? All I am doing is new gaskets and paint. Head is not coming off.
