    check the valve clearance these engines are bad about comming out of adjustment. if that does not fix it the compression valve on the camshaft is not working properly. valve adjustment usually takes care of the problem though. and questions hit me up i can help you more.

    Replace the battery with a known good one and try it. If it doesn't work then you can run an amp test on the starter. I think by taking the plug out the starter and or battery is at fault.

    You will most likely find the valves needing adjustment as GM said.
    Below is the procedure and spec.

    Remove the valve cover then rotate the engine over by hand until you reach top dead center compression stroke, Then remove the spark plug. Once at TDC insert a small screw driver in the plug hole touching the piston and rotate clockwise past TDC until you see the screw driver move down inside the hole 1/4". Now loosen the jam screw in the center of the adjustment nut and adjust to .005-.007" both intake and exhaust. Hold the adjuster nut with your wrench while tightening the jam screw. It may take a couple times to get it right because when tightening the jam screw it could throw the adjustment out so check after tightening.
