I agree. I'm in 2 minds about it and a refurb. Part of me says now it's working, leave well alone, playing will consume money needlessly and may break things! The other part says it's an old saw that although my gut says has had an easy life and is not worn, I reckon it possibly hasn't had much maintenance in its life either. I'm sort of leaning to working out what bits might be worth renewing/servicing and doing the jobs one at a time, keeping the saw together and running, just do a job at time. Haven't worked out the list of jobs yet but first stab would be, new fuel line, new oil line, new AV mounts, carb kit and service the carb, I think there's' some rubber intake boot thing on this saw, if so that's something to renew, err what else? Erm, impulse line? That would be the fuel side all renewed. Nor sure there is anything electrical worth doing beside the new plug it's had, err new coil? Then there is the damaged plug threads.... If I decide to do a more permanent fix I'd remove the cylinder, get a better thread insert inserted, refit cylinder deleting base gasket, think someone said something about new rings, caber I think. Might need some new clutch springs, although I seem to have stopped the chain creep now, bar has some life but gonna keep watching for a bargain rollomatic and after all that, or might get a lick of paint.
If anyone has any comments on that I'm all ears, although I will probably be asking on ope or the chainsaw forum here.
