I stated in the other thread about possibly a 790, 890, or 797.
I thought I read that the 790, 795 and the 800 series gear-drive counterparts were 123cc's but the acres site says they're 103cc's. Although 103cc's isn't small, at this point I'd rather look for the bigger 797 or Super 797.
I do plan on getting a few Mccullochs like the 790 and such down the road, and possibly a 990G or something, but for now I'm looking for a 797/ Super 797.
The vintage saws grow on ya!
