The mighty stihl 064 and early 066

[hacskaroly]

Yours probably gets used. This one needs to get out more but I usually just grab a different saw.

It doesn't get used as much as I would like, I ended up rebuilding it after the previous owner caught it on fire. There are a couple of screws busted in the case and screw holes that need to be retapped. I don't have a tap set yet, so it just sits for now.

For the money harbor freight icons are really good. If I wanted to go better than that I'd just buy the individual high end taps sold locally.

New build. Stihl needs tuning but cuts nicely.

Odd looking clutch cover, is it off a 661? 441? 361 even?

Odd looking clutch cover, is it off a 661? 441? 361 even?

Possible, it is a nos I just pulled out of the box. The one that was on the saw when I got it is pretty rough and went in the mag repair pile.
1138. I think I used it cuz it looked close to the one on my RE.

Yeah, looks like 661. They'll fit the 064/066/660 cases fine but sometimes there's a small gap just under the PTO side top cover screw.

Don’t the 661s have captures?

Nice red light!

You're right - it's the large cover for 361/441. The 661 comes with either captured bar nuts or without. All of the large 661 covers I've seen do not have captured bar nuts.

I found a good couple 1122 648s so will swap

My 661 has the captive nuts.

My 661 has the captive nuts.

Some do, some don't. My timber cutter buddy has three 661s and all three have the large OEM covers that came on the saws without captured BN.

Someone besides me using a max flow under the stock HD filter cover?
I really don’t like the max flow cover for the 064/066.

Not me (yet), did the HD cover require modification for the max flow filter to fit?

To make the filter fit, you have to modify the cover. And to improve airflow to the filter, I modified it further. You can only see these changes if you look very closely.

Here is the saw with the stock HD cover

 

[ferris]

U can only see the modification when u know where to look.

 

[ferris]

Green rings are the area where the filter can’t suck fresh air. That’s why the max flow cover is wider.

Cover with removed rips and so on

I have an Egan foam filter on my 064 that I have been satisfied with. It fits under the stock cover without modification.

And, most likely has better air flow around it…
