Jonsered 930 Power Issue

[Johnwell]

I have a question about the Jonsered 930 and other large saws: should the power of this thing really ‘wow’ me? Or is something wrong with mine?

I have a few other saws, including a 550xp and a slightly modded CS590. I picked up the 930 to do some hardwood milling; and while it is a torquey brute that milled 20” cherry and walnut quite well, albeit slowly; it doesn’t seem to have the oomph I would expect over my CS590 considering it’s ~50% larger.

I don’t have a compression tester but it starts and runs well. It’s honestly hard to pull over. I have it tuned by ear to get four stroking at the higher RPM’s.

It cuts through wood faster than other saws listed; maybe my expectations were just too high? I have a 7 tooth sprocket now, should I go to more teeth to get higher chain speed? I guess I expected this to be like when I went from a husky 445 to a 550xp, but it was more like going from the 550xp to the cs590.

I doubt there's anything wrong with the 930.
The bigger saws are only noticeably faster in big wood, if you bury a 28 or 32 inch bar on the 930 and the 590, the 930 will be a lot faster, in 12 inch wood they're likely the same speed.

What size timber is being cut in order to wow you?
If you are using the old 930 to cut timber the 550 could easily handle- then yes, the 550 will do so better and more comfortably.
However, if you were to fit a say 28 inch bar to both and run them with the bars buried- then the 930 wins.
Horses for courses.

I do have a 28” bar on the Jonsered (couldn’t imagine running anything over 20” on a 550); the logs were probably 18-20” in diameter (which is about average for me). I was just expecting it to really rip through; but I guess that makes sense. I just always hear the arguments for larger saws even in smaller wood and assumed there would be a more noticeable difference.

You are also comparing a couple of generations of design difference- 2186 will cut faster than a 930 same for same.
Compare your 930 to a Husqvarna 50 Rancher rather than the 550 and see what you think?
