Good lord Gregg, thats probably as loud as that 71-A is.
I took this old Mono apart last night and I think I can use the roller nosed bar on the 71-A. Its only a 24" or so and might be easier to control with the smaller wood at most GTG's.
LOL, I don't think it will match your 71 in the noise department, or power.
It does have a distinctive bark to it though. I noticed that the exauhst deflector on this one, points it to the ground..If that helps any.
The info plate on the top cover is missing on this one. I think Thomas thought it might have a smaller top-end on it, than the 92.5cc that Acres site has it listed as. Kind of the Farm, Home, Ranch type saw of its day.

Gregg,
