I'm taking a look at a neighbor's 2 stroke edger that won't run. Initially, it was almost seized. There was plain gas in the tank, rather than a 2-stroke mix, so my first thought was that he scorched it. I managed to un-seize it by putting a little Blaster in the cylinder. Cleaned the muffler, carb, flywheel magnets and coil. Got it to start easily, and it ran for about 10 seconds, and then seemed to seize again. Put in more Blaster, and it is no longer seized, but that's as far as I've gotten. Any thoughts on it being too far gone for repair? He doesn't want to put much money into it. Thanks.
