Joe's question is valid, as usual: if you are trying to pull a light-flywheel engine over without a blade plate fitted, it will be a bit more difficult than usual. The engine's internal momentum helps quite a bit in getting it over compression.
Being on the lazy side, I'd try a preliminary test before following Bruce's advice and removing the head. If you just remove the valve chest cover you can put the engine on top dead center of the firing stroke (put thumb over plug hole to make sure you are on the firing revolution, not the pumping revolution) then check the clearance of both valves with feeler gauges. If a sloppy mechanic has set the clearance with the camshaft on the EzySpin phase, you will find an enormous tappet clearance on one of the valves. If this has happened, it means the mechanic ground 0.010" too much off the valve stem, and you will have to replace the valve.
