026 help

[hedge hog]

Received a 026 that had been sitting for several years.
Tore it down and it all looks good but the base gasket was destroyed

Was going to delete it but the squish was .10

Can I use any kind of paper for gasket to get my .10 gain for a .20 squish ?

I would just put a gasket in it if it was mine..

Yes it will get a gasket but I would like it to be about .10 thick .

What I have read is .20 squish is the tightest you can go.

My local auto parts stores have Felpro gasket material in various thickness and composition.

Use actual gasket material or brass shim stock for a gasket. Paper degrades quickly when used for cylinder gaskets especially in saws used continuously. Many have claimed they made gaskets from hard cardstock and coated it with a sealer but those saws seen limited usage. Fuel has a way of soaking the cellulose fiber and breaking done of the fibers.

Roof flashing is about .010.

If you use good oil and you are checking the correct way (using the thinnest solder possible and checking in all 4 corners) you can go as tight as 15. You need a non ashing synthetic oil like Motul 800 or Amsoil Saber. Not Stihl oil.

Roof flashing is cheap, easy to cut, and you can punch the bolt holes with a paper punch. Apply a good quality gas resistant sealant to both sides of the flashing.

You can also buy .010 gasket paper on eBay. I've got a roll of it.

Just found the roof flashing last night was .010 and going to make a gasket out of it today and mic it again
All brass shim stock is to narrow to use

Then I need to do a muffler mod

Any good ideas, never did one that was this open or old.

Make one slot out of the four holes in the outlet, cut the adjoining metal away with a cutoff wheel on a Dremel, I have done this on every 026 I have owned and done up, that`s more than 40 of them by now.

Didn't measure it to see if I could go bigger ,I like to go off of the noise level
Rather max flow.
Thanks for all the inputs!

That's all you want for that saw.

A crude measurement from the screen indicates the new outlet = 80% of the inlet.

Are you going to run the spark screen?

 

[pioneerguy600]

Another mod for that muffler is to slip a 5/16' slot blade screwdriver in under the opening between the grille and muffler body, rotate the screwdriver to lift the grille and make the exit hole wider. The exhaust gas has to make a near 90 degree turn as it exits the muffler body and making the exit path a little wider sure helps.

Nope!

And I did the screwdriver to help push out in front instead of hitting the bar with exhaust

Thin business card or a few sheets of notebook paper folded over.
