Cant seem to find any sh 18s for sale anywhere, mine quit running. I tried factory needle settings, new plug, new fuel, i disassembled and reassembled the engine while sealing it with permatex ultra black gasket maker... when i took out the piston sleeve there were a few scratchs on the inside of it... smoothed out with very very fine wet sand paper... i even re pinched the sleeve to get my compression back and still will not fire up at all. Used to run great untill i had to go away for a bit and when i returned home someone had messed with my needle settings. Hasnt really run right or at all ever since.
