Thanks Bruce.
If possible, I'm also after a new bar - not sure which part number it would be but the saw is only going to be used around 4-5 times a year for camping trips and the odd backyard job. The current bar (20" I think) is cactus but doesn't have a sprocket in the end.
Might as well get a new air filter while I'm going - 214226. Or can the existing one be cleaned and re-oiled?
Cheers
