Chainsaw Repair

Yep on the west coast where you are in B.C. loggers running big long bars and 7 hours a day working in dusty thick bark red cedar and fir calls for a HD air filter.

Completely opposite here in our clean thin barked white spruce with 18"-20" bars the 064 light duty air filters were my favorite.
In fact I converted both my 066's to 064 non air compensating carbs and filter setups.
One of the reasons how I got my '92 066Mag down to the weight of a MS461.
These are my favorite pics of my 1992 and 1997 066's.
'92 is wearing a 20" ES Light , 8 pin rim with no dogs, 064 flywheel and rewind  and '97 a early non air compensate 064 HD filter setup , 28"ES with dual dogs.
