Chainsaw Repair

I know I'm ressurecting an old thread, but I'm cruising through old topics & this one brought back memories.
I had a 2100 in the early or mid eighties.  That thing would CUT!!!
BUT, it had horible vibration issues.  I was using it to cut up log truck loads of firewood & only stopped for fuel.  At the end of a tank of gas I would literaly have to pry the fingers on my handlebar hand straight
We parted ways for something less efficient but more comfortable(don't remember what now...).
