I have been toying around with the idea of purchasing an Alaskan mill or the like. But first I need a monster saw. I was thinking that an 066 would be about the smallest I should get. I came across one in a Pawn shop and he was asking $225 for it. The thing had lots of wear on it but had really good compression. Didn't have time to pull the muffler so I don't know how the piston looks. Now on to my question... Are there any big bores that I should stay away from for any reason? I don't want to buy one with hopes of rebuilding it and not be able to find parts.
