Praying For Mantis

So after some effort (new fuel mix, cleaning plug) and quite a few pulls on the starter cord, our Mantis will start (with choke pulled out) but will run for only a few seconds. Although with the fuel line pulled out of the tank the gas will indeed drip from the line, I suppose that the short run time means that only the primed gas is being used. I removed the exhaust port and found a small screen behind. Would this be the spark arrestor screen?
Any advice will be much appreciated.

Seems like that would be the spark arrestor. Clean it out if it looks plugged. Since you should be able to see in the cylinder now, look for any scoring on the walls or the piston.
You might try turning the adjustment screws in while counting the turns until they seat. Then back the screws out one full turn past where they were, then back in to where they were originally. This just might dislodge some buildup and let it try to go. Chances are the carb will need serviced with a good cleaning and kit.
