I would be finding out why this happened before I did anything else.

Was it the mix

To lean carb setting

intake rubber boot and impulse rubber seal leaking

crank seals leaking

air leak at base gasket

Just some things to start checking

Everything was tight when I took it all apart.  No obvious signs of leaks (dirt streaks where air was getting in or out), so I'm not sure.  What kind of oil should I be using in the mix.  I generally use the stuff I get at my local home center.  It's 2 cycle oil for small engine mixes.  Is there something better?  I just figured oil is oil.  Even if I have to spend $120 on a piston/cylinder kit it will still be cheaper than a new saw.  And this has only cost me about $50 a year to own and that includes chain, gas and oil.

Jim, your piston looks toasted,  time to replace. 

The jug can probably be cleaned-up with some muriatic acid.  Apply it carefully only to the areas covered in nikasil, avoid letting it "sit" on any aluminium part of the piston.  Take your time,  clean a small area, then another, etc. to avoid letting the acid run in to the ports.

I think that your 55 has the 'more desirable' closed port cylinder, which makes it even more worth trying to save.

EDIT--As mentioned,  test it for leaks so that it doesn't get cooked again.  I have a 51 (baby brother of the 55), which is not a spectacular saw,  but I consider it to be a solid dependable saw.
I'm a chainsaw hoarder & tinkerer.  The brand isn't usually important,  if the price is right I'll probably buy it.

My suspicion is there was something wrong with my mix - not enough oil.  Anyone recommend a good oil to use? 

I'll probably replace the cylinder too going on the premise that if the piston is that cooked, it likely has gotten the cylinder out of round enough that the ring won't keep the pressure up like its supposed to.  Lack of pressure means lost power, and that will put a strain on other parts of the saw.

Just curious, why would you put that much money into the saw when you add a little more to it and replace it.

Looking at the crankcase, this saw has had a lot of dirt ingestion and there is also no signs of oil on the shoulders in the crankcase.

Also looks like no oil present on piston as it died, not burnt to it. Think about the dirt ingestion on the bearings and that wear and then looks more and more like time to upgrade.

I thought about it.  The piston is less than $100, carb rebuild kit is $15.  The inside of the crankcase is clean, although there is some discoloration on the internal parts that I think is from the mix.  I'd have to add $200 for a new saw of comparable size.  Besides, I like taking things apart, putting them back together and seeing if I can get them working properly again.  It's the challenge!  Soon as I get the piston and get it back together I'll post pics.

I am just a newbe but the way I understand it those pistons like you have are very hard to find.That should be a windowed piston.I would trade you a new piston,cylinder,wrist pin and ring for 55 husky 46mm for your old cylinder and piston.Tje new one is a chinese open port but I have had good luck with these.

Jim,  if the 55 jug is salvageable & has the closed ports, it has some value to the folks who like to port chainsaws.

It might have been man of stihl. He bought a closed port 45mm or maybe 46mm closed port p+c from Baileys back a year or year half ago.  They were still out there new and  aftermarket if you knew how to look for them.  ;)

One of my carb bolts will not tighten up will I be able to repair treads in the intake houseing or should I find another part? While I posting I have rebuilt Zama carb had it pressure tested it does not seem to want to adjust seems to be flooding while it's idleing any thoughts or is it sucking air at carb mount hope you guys don't think these are really dumb question I in the learning process on a saw rebuild Thanks .

you can put a nut on a bolt and use your damaged intake manifold.....if you got the right parts
