Just picked up a complete low compression 064 for $180. Pulled the jug and have transfer on both intake and exhaust sides, haven't checked anything beyond that but I'm planning on replacing the seals along with the intake boot, impulse, fuel lines. While I'm in there should I go ahead and go with an 066 cylinder or one of the aftermarket big bore kits? Rest of the saw is in very good condition, nothing cracked or broken. Does need a new air filter, the one on it is basically a mesh screen now as the flocking is gone.

Make sure the crank bearings are good and not loose in the case. Seals are a given on a saw that old.
Bearings feel tight and roll very smooth. I'll definitely look harder at them when I get deeper into it, even the factory AV bushings are pretty tight still. I don't think this one has many hours just got some bad gas and got hot.
anybody have the part numbers needed to go to the HD air filter setup?

Stick with the 064 jug and slug I wouldn't do a big bore on it if you can do a wood's port on it and call it good they can rip without doing a big bore on them.
Best running 064 I've run had the original topend.

Exactly I've got mine and I'll most likely never get rid of it if it ever needs work I'll fix it there just that good as far as I'm concerned and well worth it.
Stihl made a kit to change over to hd setup, # 1122 007 1031, not much available from the dealer for the 064`s around here.

Yep he's going to have to serf the web I've seen them on Craigslist but there not giving them away and you have to buy the parts separately and it adds up quick.
I bought the last set my dealer could find about 3 years back, he can`t find hardly anything for the 064 through Stihl Canada. There is something like 9 parts needed to change from regular to HD filter setup.

Mine came with the HD version when I got it witch I'm really glad it did. He can still get the parts here in the US but $$$$$. Lol
Thanks, got the parts coming to get it running again. Needed an oil pump worm gear as well
Just waiting for some parts to show up, I'll try to get some pictures as I go about reassembly.
Pulled the seals tonight and found the clutch side bearing has a broken cage. Anyone have a step by step to changing the bearings and maybe some part numbers? I do have a pretty good bearing house in town

Well that's a bummer you're going to have to take it all apart and split the case get a case splitter that will make things a hole lot easier bearings you should be able to get those at a stihl dealer.
Got it split and new bearings, gaskets, seals in yesterday. Overall not a difficult process just used the hot/cold method to get the flywheel side on the crank and pto side in the case. Used the oil pump to get that bearing seated at the right depth, took a few whacks on the crank ends with the soft mallet to center it up and everything is back to rolling smooth. Found a cheap splitter kit on ebay, worked great and left the bearings in the case halves which saved me the trouble of digging out my small bearing splitter.

Melted piston started the whole thing then I found the broken bearing cage when I pulled the seals out.

Good job she should last you a long time now I'm sure you're going to replace the intake boot and inpoles line while you're in it that far cheap insurance.
New hoses and intake boot are ready to go in
Been a while but got it most of the way back together, does anyone know if the intelli-carb snout should have a rubber boot or gasket on it for use with the HD filter base? Can't find any reference to the boot but with the HD base having a hole for the intelli-carb on the clean side of the filter I feel that one should be there.
