Thanks, everyone. I'm no expert, and I should have put that disclaimer on the article. I've done a few of them lately, finally got the hang of it, and I thought maybe someone could benefit from my mistakes. I must have sent the pics to Mike out of order and he's fixed it now- it makes more sense this way.
Ron- JBF's right, but I'd bet on broken springs in the drive clutch. You described what one of mine acted like with three busted. Unless your an Attex purist, I'd go with the Duster. They're a great clutch, easy to get parts for and easy to work on. Comet has great PR and customer service, too.
If you get a kit for the 910, purple rollers are what came in the SC from what I can gather (sorry, never did find the right part number for that kit, mine came in bags that weren't labeled). Or you can always send it to me for a rebuild.
Stuck in the seventies- not in the swamp.
