If its the OHV engine, check the valve adjustment. Mine did the same thing until I adjusted the valves correctly. There is a decompression bump on the cam shaft, if the valves are too loose, the decomp doesn't work.

Ditto on the valve adjustment.  I would also look to see if the valves are even moving & then for carbon deposits on the head.

Check the decompression like has been said.  That's probably the issue.  Do you have good strong battery cables?  Sometimes you can get enough to spin an engine without the spark plug with crummy cables, but with compression you can't get er done.  I've been there and seen that on my machines.
