Finally Found a Reasonably Priced 064 - Now What?

[bulletpruf]

This popped up on FB MP for $600 then dropped to $450. I picked it up for $400. Have wanted one for quite some time now to fill the gap between the 044 and the 075.

S/N appears to be 123965831.

Anyway, it's a runner. Saw has seen some use, but tank looks good and the case doesn't have any damage. Handle and muffler cover appear to be the only non-OEM bits.

Now I have to figure out what to do. My normal course of action on a new-to-me saw is to install fuel line, impulse, fuel filter, air filter, compression test, lube clutch bearing, pull the flywheel and clean ignition bits, and rebuilt the carb. If compression is on the low side, it gets rings and prolly a BG delete while I'm at it. I'll probably do a muffler mod of sorts, too.

Once I've gone through it, I think I have a nearly new 28" Tsmura bar some some 3/8" chain for it.

What did I miss? Also, what's the deal with the big bore kits for these?

It was Made in 1991

I think your find they run good as they are .

But I'm sure some peeps will help you along and make moar gooder

Big bore kits usually have lackluster port shapes and timing, and typically make slightly less power than a good factory jug.

If you want more power delete the base gasket if the squish checks out, and give it a mild porting job. Don’t throw a fatter china jug on it.

I would certainly do a pressure vacuum test, to make sure the seals are tight. Would hate to burn up a nice saw due to an air leak.

I'd be real tempted to send that thing to Tree Monkey

That stock cylinder can be made to run harder than any AM and even most OEM 660 cylinders.

The one I have that you built sure can pull some chain.

Glad you like it. It’s a beast.

Here's one that I restored:

The buyer burned it out in a year by straight-gassing it. I replaced the top end and it's still in business after three more hard years of work. The new top end was for an MS 660 and that worked with a new top shroud to allow for the decomp to work. It looks a little goofy but that meant nothing to the buyer.

Ok, so I'll hold off on any aftermarket big bore stuff.

Will work on sourcing some OEM bits for now; just maintenance stuff.

Thanks for all the input!

Big bore stuff would be a downgrade if your top end is OEM and in good condition.

Spent a few minutes checking it out this morning.

Piston is minty.

Compression 150.

Muffler has a single port on the PTO side, inner baffle is intact.

Nice!

Advance the timing a little, get the baffle out of the muffler, and the muffler matched to the jug. Then add a dual port cover. Run it.

Sounds good to me!

Thanks

Anyone know where I can find a genuine Stihl HD air filter and pre-filter for this saw? All I'm seeing is aftermarket stuff.

You won't find Stihl parts online. The aftermarket filters ain't bad though.

Haven't cut with it yet, but I did get a dual port muffler cover for it, OEM HD air filter/pre-filter, a new set of OEM dogs (was missing one), the larger sized OEM clutch cover, a new OEM 3/4 wrap handle -- had to order from Outbushman in OZ -- to replace the reproduction half wrap that's on it, and a few other odds and ends.

Sounds like you are making a nice saw of it.

I got it for a good price so I figured I could afford to spend a few $ on it.
