Spent some time this morning finishing up the work on 2 Jonsy saws.
The 930 Super didn't take much as it was pretty clean to begin with. Just a little wiping down, replaced the fuel and impulse lines, and filter, reassembled the wrap handle and spikes (thanks to thechainsawguy). A quick glance at the piston through the exhaust shows the piston to be near new. I bought this saw years ago, but never ran it and I still haven't.
The 910, I got off Ebay and it turned out to be nicer than stated. I ran the covers through the dishwasher, cleaned a ton of oily sawdust off, replaced the fuel/impulse/filter, and fixed a little wiring.
During this little project, I got real familiar with the differences between the 910 and 920/930. We all know from SawTroll that the 910 was the last pure Jonsered. Obviously, the handle system is different. I'm not sure that mounting the front and rear handles independently is such a smoking hot idea but it works. The 910 has a compression release, though mine is missing and blocked off. The coil for the 910 is part of the spark plug boot, while the 920/930 coil is mounted in the carb box (either way is unusual but I wonder how interchangeable the 2 systems are?). The recoil on the 910 is metal, the 920/930 is plastic. Strangely, the rear handle on the 910 is plastic and the 920/930 is metal. Seems like a step backwards, but the 910 handle doesn't feel very sturdy. The air filter on the 910/920 is the flat style, single-bolt, impossible to find POS. With the 930, you have more options--a 288 Husky filter will fit, but you cannot reinstall the cover. I believe a 670 Jons filter will bolt right up and will find out soon. Mufflers are all more or less the same and will interchange I think. The top covers are different due to changes in the air filter and cylinder. The 910 has no chainbrake though it was clearly an option for this saw.
As a side note, the mount locations of the 910 wrap handle make mounting a chain a bit tricker than the 930.
Take care, Chris B.
