Hello I would be most grateful for any help with the following.I am anxious to get a user/ service manual for this saw and a spare parts list.The saw despite being purchased in 1983 has had very little use and has not been used for the last 10 yrs being stored stored in a dry garage with the gas tank empty.It starts with no difficulty but cuts out when the throttle is reved.The chain runs rather fast even when idleing.I guess the carb settings need adjustment but am unsure how to proceed with this.I am guessing that the H L and T screws are for this purpose.Apologies for ignorance but help much appreciated.Have just installed a wood burning stove and getting rather chilly although sawing by hand is keeping me warm.
