If your motor has an overhead valve (OHV) engine then most likely you need to adjust your valves. OHV motors have a small compression release that allows your battery to overcome the compression so that it can crank your motor. If the valve clearances get too high (and they do overtime) this release doesn't happen and your motor will "stop on the compression stroke".

Obviously taking out the spark plugs releases the compression as well so the motor cranks without problem. Unfortuneately, as you know, you need spark plugs to run.

On an additional note, you should always state your engine type, manufacturer and model number when you post about operating problems.

I agree, your valves need to be adjusted. Set them both to .005" with the piston 1/4" past TDC.
