Anyone ever make a Muffler Gasket?

[Jeff Lary]

I need to make a muffler gasket for my Partner 500, well at least I think I should? I am worried about the possible sucking in some air and harming the P/C. I have made one in the past by stacking 4 pcs of 10 tho shim stock (last week in fact). I am wondering if you could use thick gasket material instead? I think if it was sandwhiched tightly inbetween the muff and jug It would not burn out, (lack of air to combust? ) Anyway if you ever made one tell me what you used metal-beer can? / or fiber of some sort.

Just made one the other day for a Homelite I'm working on.

The saw originally came from the factory with none (according to the IPL), but there was plenty of evidence that the seal wasn't very good.

I cut a piece off a sheet of some Mr Gasket high performance stuff I have. Has metal mesh in it, so trimming was done with tin snips and the interior was cut with a Dremel.

After the welding repair to the muffler is complete, I'm thinking it should work out well.

Beer can. Cut off ends, vertical cut, roll flat, and cut. PM me if you need an empty beer can:msp_biggrin:

You can buy graphite coated/impregnated gasket material in various thickness's from Ebay some has wire/foil in the centre some doe`s not I have used both types with no problems, googling [exhaust gasket material] will get you up to speed with what is available

I think NAPA carries bulk gasket material you can use. It is the thicker mesh reinforced type. I have a sheet of it that I have cut several from. A tiny leak at the exhaust port is not much of a problem unless it is leaking on to your plastic and melting it.

Permatex Ultra Copper.

Later AMC engines came with no (or few) gaskets. The exhaust manifolds used no gaskets and the surfaces were machined smooth. I always used Permatex Ultra Copper on my 360 manifolds. On one of them one of the rear exhaust port studs had broken off. I pulled the manifold and coated it with Permatex Ultra Copper as a temporary repair. I never got around to fixing it and it held fine for years. You only need a thin coating, no need to overdo it.

By the time I get done gutting the mufflers on my saws a gasket is the last thing you need:biggrinbounce2:

I guess I never gave any thought to searching out new material maybe I will. Thanks Jeff

Well there ya go, I was wondering how signifigant it was if there was a leak at the muffler contact point ? I understand leaking around the carb being not good.Thanks Jeff

Multi Quote ?

Well if your reading this you can see what I have done here. I answered each post with a seperate post/ reply. Is there a way to reply to each person in one post ? is that what this place calls a Multi Quote? and how do you do that?

A piece of gutter off ur house of home depot sells them and all kinds of aluminum flashing.If you have a punch set sharp enough u can punch out the holes or drill em, dremel etc.

i made one out of an old graphite head gasket from a car i did the head gasket on. worked good. better then oem. the only thing is that the head gasket has some kind of sticky sealant over the graphite that really melts when exposted to exhaust temps. was pretty well glued to the cylinder next time i removed it. had a bit@# of a time cleaning it off. did the same method the next time but torched the sticky stuff first. it hardened and made a really nice seal. won't know what kind of a mess it made til next time i take it off. did one on my 3120 a couple weeks ago. used aluminum flashing and it worked great :msp_thumbup:

:hmm3grin2orange: damn I just :hmm3grin2orange: my azz off at your expense Randy.

Yes like I said earlier I did make one already from shim stock so I knew that would work but look at all the great ideas I have now besides that !!! yea for me.
