So, a guy asked me to have a look at his old 024.
It has a weird coil/trigger setup, Stihl parts number: 1 217 280 113:


It has a non-adjustable always-on oil pump, which doesn't use the typical gear driven by the clutch drum:

It has a single 1,5mm piston ring.
I cannot find a IPL or workshop manual for a Stihl 024 with single piston ring, always-on oiler and the weird ignition. I suspect it's a pre 96 saw? Does anybody have an IPL or workshop manual for me, please?
The owner told me, the saw wasn't oiling. The gear on the shaft came off very easy, so I suspect the gear turns free on the shaft. It's just a press fit, no key. I'm thinking about reinstalling it with a bit of Locktite. Any other ideas?
