Picked up a Poulan pp4018 at a garage sale for $15 this weekend. It came with the bar, chain, and case, figured for the price, what the hell why not. It was definitely used, but not too bad looking. I did notice though the plastic cover on top, showed signs of melting a little bit where it just covers over the muffler. Some of the plastic there got scorched. But the rest of it looked perfect.
So I took it home, put fresh 40/1 mix and tried to start it. No love. I then took it apart, found that the spark plug literally had no spark. Before concluding a I had a bad coil, I borrowed a plug from another Poulan saw, and 36cc, and put it in my garage sale saw. It fired up on the 2nd pull. The carb was way out of adjustment so decided to shut it off. This is where I quickly noticed the muffler was hot. I know they warm up quick, but I was a little concerned. This hadn't even been running for 1min. I decided to replace the fuel lines, filter, cleaned the carb good, and fire it back up, this time tuning the carb appropriately. Again it got hot within the first min.
So I'm happy I got this thing running, and for $15 I'm very happy. But I'm a little concerned about the heat. Has anyone experienced this before? One of the other things I noticed is when it revs high, I mean it revs high. It doesn't feel like a normal 40cc saw. I'm curious if maybe someone modded the muffler or something on this one cause at full throttle its screaming. I decided to shut it down and let it cool down.
While waiting for the cool down, I noticed the sticker on the back, the VIN, or whatever that's called, was clearly is labeled a 42cc made in 2006. But the plastic start & bar covers clearly say 40cc. I don't know if the previous owner swapped plastic at some time in its former life, or the factory would have snuck in a 42cc and labeled it a 40cc. I trust the sticker more than the plastic covers.
