Chainsaw Repair

Sabre had some strange stuff...
I think they experimented quite a bit with the chains.

It is 0,01" shorter than .325. That is 0,2540mm On ten drivers it is less than 2mm.

Not sure if it is any different to run, it depends a bit of how the driver seat in the rim/sprocket.

You should ask the guy's who sold these in 70's perhaps early 80's what they think.
A couple of them are saw collectors and read a lot on CSCF.

Sven Johnson would be my best bet, he can likely say for sure, unlike me that speculate...

A PM to him could be a good idea.
