Oiler questions about old STIHL 026 chainsaw pre1990 models.

[Berte]

I was a having oiler issues with my Sthl 0256, I replaced the oil reservoir vacuum hose and the bar feeder hose, seems to have resolved the issue. My saw does not have a slotted clutch cover or oiler pin worm gear. Is that common for the early Stihl 026 chainsaws?

yes, the pro series had an adjustable oiler, the one you have is a constant oiler.
see the attached IPL for the difference.

hope this helps.
Good little saw too.
