Now you're talkin' about a Stihl I can warm up to...Fun, fun. Always lights up my day to fire up my sweet old 064...and man can it make quick work of 40 inch firewood rounds.
Love my 064...
Old school.. Kolbenschmidt cylinder..

Burnham, I found the other 064 crankcase complete with good crank I have, it was a broken saw run over by my partner's skidder. The serial number # is 117584561.Almost didn't find the 064 in the storage shed, the kids were playing with every flashlight I own............... but the smart phone had enough light.
Serial #116468370. I'll dig out the 064 spare crankcases later, my wife and I are leaving at 6 am to go house hunting will be back thurs night.






I took mine off. Too much friggen around cleaning and oiling for my tastes.
My HD Stihl filters work just fine and blow out with air quick. Never really noticed much of a performance difference Jed.
More performance to be had by opening it up exhaust wise or porting. Maybe up the compression with a gasket removal.
I know.. Stepping in here adding my 2 cents
  The HD's are a lot tougher though.  Don't discount the Max Flow though.  I swear they make a big difference, and the white one (in good condition and well oiled) is always gonna filter every bit as much as the HD.  The green one imho has a little bit TOO much porosity, unless you know that you're only gonna be in green wood.
Think I said that...though the part number is better info than I had at hand.
  Funny: even though it's a brand-new (7 months old, and used about every other day) saw the darned big screw on the muffler was already loose (The big screw nearest the guide-bar--I'm just talking about the outside muffler cover.  I didn't take the whole muffler off).  I put some blue masking tape over the six holes on the weird little baffle thingy inside the muffler so that I wouldn't get any shavings touching the piston when I hogged the outside hole open to about 15%.  I was thinkin, "I wonder why you wouldn't need to hog out a couple of the six weird little holes out as well," but...  no matter.)  The little plastic limiters came out easily enough on the carb, so...  I guess I'll richen em both up a tad and see how she goes.  
Cheers Jed, ok sure I won't write off the Max Flows, when I start noticing I have spare time for more saw maintenance I may switch![]()
