Okay I bought a 341T off a guy on craigslist he said he only had it 11 months and he couldn't get it to idle right and he wanted to get a stihl. He got it started and ran it a little so I decided I'd risk it and brought it home. I messed with it some and then took the muffler and spark plug out and the end of the piston is covered with gray gunk almost the consistency of creasote and I can see oily residue on the cylinder wall. I got it to run pretty good for a minute or less and then when it gets hot it dies and it won't run more than about 10 seconds after that. If you take the spark plug out it is covered with that gray gunk and soaked with gas. I almost wonder if he fried it or something. I'm becoming fairly sure it's more than a carb adjustment issue but what do you guys think? I didn't pay much for it so if it's junk I'm not out that much.
