Burnt03, as PB posted the metal CB arm appears to be the correct one.

I ran into a problem with some of the early CBs with the metal arms. I don't know how common the problem is, but I'll share my experience, at the risk of sounding like a broken record/CD. The knee-joint, the part that holds the CB arm in the Off/Disengaged position, can become worn/fatigued, and will allow the CB to slip into the Engaged position. On some covers the knee-joint problem is obvious, on others they'll seem to hold just fine........until you put the saw in wood.

At least one member here was going to experiment with repairing the knee-joints, but I haven't heard how that turned out.
 
630 chain brake

Here is one I just finished for a 670. Purchased the 61/268 cover from sponsor Northwood, sliced off the back with a die grinder, and painted it red.
 
No the back of the cover is closed and it has the rubber flapper to deflect the chips. After you cut off the back piece it looks almost identical to the 630/670 cover.
 
From the factory? That's the first I've heard that. I'd always assumed my 930 was retrofitted (and that may still be the case.) The bar cover is sloppy on the studs.

Yes, from the factory. From the best I can tell, it happened around 1986-87 but not positive on that. According to the IPL's the bar stud switch occurred between February and August of 1986 but I am not sure how accurate those dates are or if they were updated after the fact. I always wondered why the 830/930 saws were listed in the Oregon catalog with both the D024 and D009 mount. It could have been both.
 
Zero knowledge of J-reds but thought this might be a good place to check for a rear handle for a Jred 2095 for a buddie's saw. His is split in half w/ trigger assembly, throttle linkage gone.

Spike60 (still a site sponsor?) helped Mastermind with parts on a Jonsered 2095 rebuild; site sponsor Chainsawr is also a good source for hard-to-find parts. I'm thinking that the 2094 rear handle should be the same.

Thanks for the help guys. Was hoping I might find a used one. Definately a different set up than my 395 was handle is independant of the tank.
 
Is there any way to tune it up to run a higher RPM or would that be stupid?

You mean by leaning it out? You'd just loose power and burn it up. Tune the H side per the instructions in my sig line. These older Jonsereds saws are very strong runners. If you really desire a high RPM saw then sell that Jonsereds to one of the guys here and buy a newer Jonsered or Husqvarna (or Dolmar or stihl)...

The 90 is an older saw designed for torque, not designed for speed. While I'd be curious to know if anyone has gone inside a 90 to see what if any mods were possible, I'd tune it properly (not on the "razor's edge") and run it for what it is, a cool vintage saw.
