Stihl 064

To be honest, when things look that bad as shown on Post #14, I replace them both with a P/C kit. Just MHO.

When I can afford it, I do, when I can't, I clean it up as good as I can and go from there. I have had pretty good luck so far cleaning up cylinders and just replacing a piston and rings.

I have a 391cylinder I am working on that looks like yours. I found a video that showed an option for removing aluminum without using acid. I gave it a try and I really liked the results!!! I will probably need a new piston and rings though.

I've been happy with the results using this technique too.

Hi all, I have had a look at the cylinder and have tried the method suggested. It works really well! Unfortunately there seems to be a fairly large gouge in the cylinder from the exhaust port all the way up to the top. I will get some pictures this evening. Unfortunately I think this means I'm going to need a new cylinder. In this case what is the collective opinion? I can get an OEM 066 cylinder and piston, or Meteor. Or I can get a Meteor 064 cylinder and piston. I have not yet found out if I can get an OEM 064 cylinder and piston, but the closeness in price is leading me to lean towards the 066 top end route either meteor or oem.

If the cylinder isn't salvageable, this is what I would be getting:

Maybe I'm the only one who has been burned by Hyway and Meteor cylinders with plating failures, but I can't recommend them. As for going 066 or 064, the 066 isn't a bolt-on. It requires the same type of modification as doing an 044/046 hybrid.

This PC kit might be a good option Dukes 066 Big bore or Dukes 066. Lots of other parts available at this sponsor's sites pages for this saw as well.

I got a Husky 576xp PC kit from Duke's for a 576 and am very happy with it. Very clean and bolted right up without any issue. Fired right up too!

I have run a handful of Duke's cylinders, and haven't had an issue with any of them yet.

The port timing of the Dukes reserve chrome cylinder is pretty nice. Pretty much dead on to early bubble tops.

Yeah those are nice. If the OP is game for making it fit to the 064 case, that would be a good option too.

Pretty sure the 54mm jug is a bolt on. The M5 bolts will just fit perfectly spaced in the M6 holes IIRC.

Well, I stand corrected

Unfortunately got side tracked away from this, but had some time to look at it again. Today I replaced all the fuel lines, and the fuel filter. I washed the tank out as well. There was definitely some water in the half tank of fuel the saw came with which wouldn't have been helping. I replaced the plastic surrounding the clutch drum as it was only a couple of pounds and the burn mark offends me when everything else is okay. As the plastic had melted I guess the clutch has got fairly hot so I replaced the clutch springs and drum bearing. I have also cleaned out the carb, and rebuilt it with new gaskets and diaphragms so hopefully that is ready to go. I have also just checked the squish which is coming in at 23 thou. Hopefully can get it back together tomorrow and see if it will make some noise!

Update?

I have never has any luck replacing just the rings only whenever the piston is worn as badly as yours is. Get a complete kit and replace both the P and C. You will be glad that you did.
