I must ask you since it's clear you have a lot of experience with chainsaws: do you think a makita 6100 might last 1000 hours using synthetic motul 2 stroke oil before considering "it's used/worn out/done"? Thanks
Case in point, I had an 810 Solo. ( Or maybe it was a 790. It was the largest p+c they could put in that maincase).
It was a cutting machine. The first one I had cut great for 10 cord. Then the crank broke. Solo sent me a new saw. The 2nd one was a great cutting saw also. Flat out cut my 460 Stihl's and 327 Western Husky.
It had enough power so I put a 36" bar on it.
That turned out to be a big mistake !
The maincase in the bar stud area was not built nearly strong enough to handle the stress of a bar that long or heavy. The main case shattered around the front bar stud. So, that was that for that saw. The engine still ran GREAT. But the saw was useless and not a saw any longer.
Different saws , when they first come out have different problems that are magnified when a long bar is hung on the saw.
The 064 Stihl when it came out had a big problem with the clutch side main bearing. The 046 kept stripping out the keyway on the flywheel side. And on and on it goes.
The first few years of the 288 Husky. Guys got rid of them because they sometimes developed too high of compression and should back fire if a guy wasn't really meaning up when he went to start them I know guys that had fingers snapped and tendons snapped in their left hand when they would backfire in the starting sequence.
I know saws that were Great. But we're so heavy or vibrated so much or were so loud. Guys just moved on to a saw more user friendly.
