Have you checked for spark? Take the spark plugs out, put the wires on them and position them so the metal body of the plug is touching the engine block – don’t worry about paint or a good connection – just let them touch. Then pull the starter and look for spark in the plug gaps.
If you have spark, then , yeah – all the carb stuff the other guys are talking about.
These models are known for blowing the headgasket, creating a path through the gasket between the cylinders, and then it will kick some but it will not start, but when this happens, the compression is usually lower than what you measured, but the compression is usually the exact same in both cylinders when this problem happens.
