Ahhhh.....I do have parts, but trying to get two 910's running and still have some parts support. I know that if these parts leave the property, they'll be very hard or impossible to find. Sorry....
The trigger handle as you probably know, has AV's that historically rip out very easily if you pinch your bar and PULL. Jonsereds even made a kit for that to strengthen the AV's. I have the kit, but only one. There are some commercial adhesives that can re-bond the rubber to the metal in many 'ripped' AV's.
The coils used in this saw got a bad rep. Mostly, Jonsereds dabbled in soy based insulation like a lot of manufacturers did, including Mercedes. This causes the wire insulation to disintegrate over time....way faster than normal. If you use a decent oil resistant heat-shrink and some of that marine quality brush on/dab on liquid insulation in the spaces the heat shrink won't cover....you'll bring back most of the "bad" coils.
