Good advice! but I'm pretty sure it's too far gone for even that!  I don't need the use of the saw (yet) so I'll wait until the new part arrives from the States but I need to get the flywheel off first so I can check out the bits hiding behind that.  Any tips?  I've tried the 'shock' method (hitting reasonably hard with the other end of the shaft on a firm surface) but don't want to hit it too hard and break anything.  I have a 2 or 3 arm puller but the arms are too big to get behind the flywheel (it's more of a car bearing puller).

 

I've got the sprocket off and whilst it seems ok, I'll probably get a new one of those - I'm fairly sure it's one of these -

You may have to grind the arms of the puller to fit unless the pawls come off or the flywheel has tapped holes in it for extraction use with a flywheel puller. Go carefully, it is easy to damage flywheels. A sharp crack with a hammer on the puller often shifts it.

Yes, I think the starter pawls are bolted down, so I could try and rig up a piece of flat bar across the centre and bolt it down on the pawl bolts then 'pressure' it off the centre shaft..... not sure when I'll get chance but probably next weekend.

get a bit of tension on the puller then tap the centre bolt usually works for me. I ground mine down to fit under a scooter flywheel and now it fits many things. If you have someone who can lever with a couple of screwdrivers you can slacken the centre nut off and give that a smart crack with a small hammer to start it off.

I tried to get the flywheel off a few times, made a makeshift puller, applied 'tension', hit it with a hammer, sprayed it with WD40 (I haven't got any Plus Gas) - nothing would shift it or loosen it (didn't try heat), so knowing the engine would start but just not run (and that was probably down to the carb rubber boot), I was reasonably happy to leave it be.  New carb rubber boot arrived today, carb overhaul kit arrived the other day so that had already been rebuilt before today, also a new spark plug arrived, and as it's a wet day, I decided to fit the rubber boot and see if I could get it running again.

 

Success!!  Engine idles fine, picks up ok, revs well.  I've adjusted the Lo screw to where I think it should be (if anything, slightly richer than maybe it should be) and the Hi jet seems happy with the standard 1 turn out.  Again, the Hi is, if anything, on the rich side, so I'm happy to leave it like that until I can get it cutting some wood to see how it does under load.

 

Just need to get some chains ordered now then have a play with some of my timber and see what I can mill with it!!  Promise to post results (once it stops raining!) - but in the milling forum.
