Grahame , every 2A I’ve ever worked on the flywheel is only held on by the starter pulley , you should see a large slot in the steel embossed inner part , I have a nut welded on a piece of steel that fits snugly into that slot and use an impact gun , it’s normal righthand thread, very often the flywheel will come of with a VERY SLIGHT tap from behind , it’s a straight shaft with key , so no locked on tapers , or air chisels to worry about. Can’t say I’m sure what you mean by the rollpin , it’s something I’ve never come accross.
