I've Been Screwed!!! MS 440 Rebuild
OUCH! I bought this MS 440 of eBay and got it today. LINK All it was supposed to need was a coil and a starter rope, per a dealer's inspection. It's also only supposed to be two years old. Check out what I got.
I put a different coil in it, fixed the starter and tried to start it. It tried to fire but would not start. The enging was very noisy when I pulled the starter rope. I finally removed the muffler and found that the piston is extremely scored. I then removed the cylinder to find that it is ruined as well as the crank. There are deep gouges in the cylinder wall. The connecting rod bearing cage on the crank is all busted up. This is what was causing all the noise. This saw is toast. You can see that the saw has been apart before. The cylinder has been honed and the piston sanded. You can also see pieces of old rings embedded in the cylinder head and piston top. These did not come from the piston in the saw. It's rings are not broken.
I sent an email and offered to reassemble and return the saw as is or discuss replacing the crank, cylinder/piston, and gaskets. I even sent links of the best deals on a used crank and cylinder/piston. I haven't heard back since I just sent it. What's your take on this?
