Stihl 064 AV Info

[mile9socounty]

As far as the coils go, if you're saw has good spark and you don't need them, someone here would probably buy them from you.

Yesterday I was finally able to put my 064 back together thanks to snow. Had everything buttoned up and ready to go, no spark. So I go strolling down to the local saw shop and see if he had any use/new coils for it. The 3 coils the WSM shows, 2 would not fit. The one that did fit, didnt have a part number. Just out of shear luck, he had a NOS coil for a 066 which did fit. 130$

So I would hang on to any parts you think you might need. Of all the spare 064 parts I have in one of my storage bins, no coil.

Did I mention that my 064 responded very well to a heavy woods port? Oh yeah! 13,900Rpm with a 32" B&C free load.

The air filter is very different on the early ones. It's more like a 026 style where the later ones are the standard oval filters like a 044-088.

Yes the 064 I have start off with the thin whimpy air filter and its weird design. Over time I bought the HD filter set up, then the hole shot after market set up. New engine shroud, AV mounts, 066 dual port muffler, and now a new coil.

What RPM is the 064 to run at? I've read 12,000 and then I've read 13,000......

No idea, but since I started porting my own saws. Stock is no longer fun. To compare it in other terms, its like comparing a .22cal to a .45. Big difference.

My early 1986 edition didn't rev near as high as my 066 so I'd say 12,000 seemed about right, although I never put a tach to it but I MM'd it and it didn't help. In softwood under say 28" I'd use a 460 as it's much faster. but in bigger wood where rpm speed doesn't help as much as torque and that's were the 064 really shines. I see no reason on a stock 064 to run a bar less than 32" I know because I tried and it was disappointing. Even though the 064 is light, there are better choices for firewood saws. To me it's more of a faller and loggers saw for big wood.

So, you would like a 064 with a 066 topend turning 15K?

Ya Brad, who wouldn't, the problem is keeping that monster alive. One reason they're light is their crankcase isn't made for that kind of punishment. When I bought mine I was gonna put a 660 topend on it but after a bit of investigating I decided to leave the saw in it's original condition. It reminded me of the days we would scrap a nice Impala, Galaxy, or Imperial just to get the big engine to put in a smaller hot rod. Not so many of the big cars left anymore so maybe it would be good to keep a few for historical sake? My old crew chief did the same with the hemi cars when top fuel was common in the late 60's and 70's. but you wouldn't scrap a hemi Challanger or Cuda today. I decided to leave a nice old saw alone. If I'm gonna risk hurting a saw then I'll do it with a newer, easily replaced saw.
