I have a 16 year old Stihl 012AV that has done sterling service and, until the other day, has never let me down. The problem was no oil reaching the chain. I replaced the oil pump and for a short while was back in business, however, after four or five refills the oiler packed up again. I have been told that the pump works off a pulse from the crank and that there may be a problem here. Can anyone shed any light on this? And does anyone have a work shop manual? so I can strip the saw and know what I am looking for and more importantly re-torque the bolts correctly.
