If that is the OHV V-twin, I'm told it has a decompression device as well as the EzySpin feature mowernut referred to. That engine will not crank unless the decompressor is working, and it will not work unless the tappet clearance is just exactly right - it seems to be extremely sensitive. So, you need to attend very carefully to the tappet clearance as your first move, to get it to crank and start.
The valve clearance, and the valves, have nothing to do with your other problems. You have a fuel feed or carburetor problem. We will need more information to diagnose that one, but meanwhile fix your decompressor before you damage your starter motor.
