Bruce, thanks for the forwarding of the parts list. My chainsaw was assembled by me from a box of parts and hence I am unsure of the serial numbers of what I have made. The parts list that you forwarded was almost right, except for the fact that the carby plastic cover and air filter cover are different to the one depicted in the drawing. My guess is that the model I have is only slightly newer or older than the one that I thought. If I have given you enough information, could you please forward the parts list for any slightly dofferent models to me? Thanking you in anticipation, Mick
