The mighty stihl 064 and early 066

[huskyboy]

Didn’t see a “definitive” thread on these saws specifically so I thought I’d start one. This is a place to post anything related to them, please post your findings, parts info, cuttin videos ect.... and whatever . I’ve had this 064 for a couple months and after some basic mods and minor repairs today was the first day I’ve really used it. Had some big oak to buck up and thought it would be appropriate for the 064. I can see why these things were such a legend back in there heyday. It’s about as fast as a hot 7900 in cut speed, but with mountains of torque to back up the chainspeed. Feels like I’m holding a slightly heavier 461 in the hands. AV and the filter system are rather dated, but they were good in its time. She likes her fuel as well, that’s why I named it Miss Piggy lol. Makes a nice racket with the loud exhaust and whining flywheel. Great saw with lots of character, puts a smile on your face.

I have an old/ very early 066 with the metal airfilter cover and an early 064, they are my favorites over my other later o66`s, just something about the way they handle and the torque they produce makes me smile every time I get them out cutting. The roar from the open low profile airfilter reminds me of the 1960`s era muscle cars I ran.

Great timing, just got an 064 in a box I will be watching this thread. Can’t wait to get into mine but I have lots to learn first. I have done an 024, and an 036 to date. I know it’s a basket case but we will see This may be my winter project

My old 064, not a looker but a real good worker.

The 066, just a bit heavier than the 064 but about matched for power.

Can you learn much from the serial number?

This is what 230 lbs comp did to the sparkplug just after its rebuild, porting and squish adjustment.

The only real stick in the mud I found with my 064 was the rather stingy oiler output for a saw of this size. Which I fixed by doing a quick mod to the oil pump so I could turn out the screw a bit further. If it didn’t work I was going to mod the pump internally. But now oil usage is now 1/1 with the gas which I’m satisfied with. It now oils a 28” bar with a 8 pin in hardwood like it should have from the start. I do wish the pump was compatible with the 660, so a guy could just swap in HO oiler stuff and call it a day.

Your using the puller tool that threads into the flywheel?

Great thread.

I have another one to build as well, have been sourcing out NOS parts for it, Bryce was selling some last fall and this past spring.

@Definitive Dave covered almost everything 064 related in threads either here or on AS. Find those threads and you'll have a wealth of already posted info.

There is an early & later 064 pump, the later pump can be taken apart just like the 066 pump & HO parts swapped in
