I got offered cash and a jonsered 920, and an older jonsered that I don't know the model for my ms250, is there anywhere to buy new parts like bearings, seals, cylinders, etc?
Wow, if you can get those running you have really scored big here. Other saw is a 621. Both well built and good runners.
Bearings and seals should be easy. Most other stuff extremely hard to come by. Especially cylinders. I think we want to see if those cylinders can be cleaned up. There are some aftermarket piston options out there. Gotta tear into 'em and see what you are going to need. I'd check spark before going too far.
Let me know what you find and I'll help if i can.
Some parts are hard to come by. Check the brake band, also the small tear handle AV pieces.
I'd definitely do that deal. Put it this way, MS250's are a dime a dozen. Chances are, you could get ahold of another one pretty easily. 920's are a big powerful saw, not that common. If the top end is good and it has spark, you could make out really well.
Don't know much about the silverback though, sorry.
920 is an 88cc saw. I had one with a 32" bar set up for milling before I sold it. 18-20 would work but it'd be a real heavy saw for that bar length IMO.Will check those parts for sure, I got the ms250 to repair and sell anyway, prefer my 445 over it for a small saw, I'm thinking of an 18-20" bar for the 920 if it ends up being a runner, does that sound alright? No hardwood around me just all softwood
Gotta love that. Covers and parts saws come up on ebay every couple weeks

Also, the bar mount is not a standard D009. New bars available I think are limited to 24" but I also believe D009 bars can be modified to work.
920 is a D024 mount bar, 10mm studs. D009 is 9.5mm so you can file the slot on the bar a little or the shoulder of the bar studs and use husky large mount bars. Just make sure the oil holes still line up.
That's normal for a 621. Jonnys from that era had domed pistons in them. 150 is a little low on the 920.
930 air filters are also NLA. But they were the same filters used on the Jonny 625/630/670 so there's a better chance of finding them NOS or used. Can't really swap filters without also swapping top covers. The 930 filter holder is also NLA. A Husky 288 filter holder should fit except it can't be bolted to the case without tapping a different hole for the screw.
I've had that theory for a while, but I haven't tried it yet I think my language should have been more along the lines of "can be made to work" instead of it fits.
I've got an 820 I'm messing with and I''ll take a closer look at this. Would be a good option for guys with 820/920's.
