Did it get over 250 degrees? If so it might be done. If you have the recipt you can send it in and they will rebuild it for free. It comes with a 2 year warenty

If an engine won't start, and you have good compression, a good glow plug, and good fuel, then it's either too dry of fuel or it's flooded.

Best way to start is to have a dry engine, choke it until fuel gets to the carb and then choke a turn or two. Throttle to full, no battery on glow plug, and turn the engine over several times to work the fuel into the engine. Throttle to idle or just above, battery on glow plug, and spin the engine to start it. It should fire. If it fires, it will run. You then need to make sure you have a good fuel supply and good fuel tank/line plumbing.

If all else fails, use the instructions to reset the carburetor to the original starting points and go from there.

If the engine's had an overheat, then it's possible that the compression fit has loosened, which means no end of troubles. You'll need a new piston/liner assembly.
