Probably not much help but I had a 150 Merc with the same issue and a stator had to be replaced to fix it

You checked compression. There is still fuel and spark. Assuming it does not sound like it’s starving for fuel then I’d check spark. I had something similar and the power pack had gone bad causing loss of spark on one side.
