Chainsaw Repair

Never thought about those type of issues.   But there you go. 

Here's a very entertaining video for anyone with a saw shop doing saw repair. I could watch the whole thing over and over again.
The living legend Bob "Walkersized" Walker at his home in Nanaimo, British Columbia Canada.
At about the 2:00 minute mark Bob gets into explaining about a 3120XP hotsaw he's wrenching on. At about the 8:30 minute mark he shows a 3120 full circle stroked crank he built.

Tune I did for the 60" must have been  good to go.  Went fat to hopefully clear up in the long bucking cuts.
H side carb.  Jason Egan woods ported.

He said the tree was 57" across, didnt measure dbh.

Then some logs set aside I guess.

I was working for Husky when this saw came out,it was so problem plagued I couldn't even keep one running for a week. I finally got the unfortunate owners to buy an 084 which worked tirelessly and faultlessly.The 3120 had a bum primer,throttle cable mounts,carb,just a nightmare of trouble to any dealer and user.It wouldn't start,run,the mounts all destructed in a week,just a total barely running pig which was falling apppart,the mounts were quickly breaking appart and damaging the crankcase. As a dealer I could not brginto fix althese faults,whata nightmare,won't start,run.It had major faults as a sw.Just a big stummbly pig,carb cant run.Had so many factory fixes the wer horribly.It as so problem plauged yjst it wasn't usefull a a dug mule job.

I've never owned a 3120 but have been around them since they came out in the late 1980's and always heard good about them.
Usually "junk saws" are run by "junk operators ".
I've seen 084-880's with burnt clutch/oil pump innards and melted plastics from their inboard clutches while milling.
But never saw a 3120 with its outboard clutch do that....
