Just a newb here, but I suppose newbs can suck too.
I just got a McCulloch 440 (yes, a 440 on the crankcase) and a Stihl 021 for $60 between them.
I also got a running Echo 302s for $15 with a new B&C, and a Homelite 150 for $5 about a month ago (pics coming)
The stihl only needed a clutch cover and sproket, plus a tank vent. The Echo needed absolutely nothing. Little tuning and it works fine. It has 1/4 inch pitch chain too for some reason. the Homelite was $5 because it had no spark. The points were simply not closing. The big Mac is the most suckage, all that was wrong was the cylinder was full of old bar oil where the pump leaked. Drained it and started it. There is no damage anywhere on it, it even still has the original rubber chip deflector. Only missing the 440 model tag.
