piston problem

[chainsawjunky]

Ok, there's a good lesson behind this. This is the top of the piston.

This is the side of the piston.

This is the bottom of the piston.

This is the other side of the piston.

Anyone care to tell me what happened to this piston?

Oven-cleaner?

Looks like wrong oil ( too heavy ) for mix and too much, or, water got into the crank chamber/piston area. Just my guess.

Muratic acid,,,,,,,,,,,,,,

That's not a piston, thats a meteorite.

Someone used regular motor oil for mix?

Left it in purple cleaner for a couple weeks?

You let one of those Aliens from Outer Space (the ones that have that aluminum dissolving saliva) get ahold of your piston. "Holy Cow" WTF
:help: :jawdrop:

hehe, yeah. My brother was watchin me clean the piston and asked me what it did. I told him it gets the aluminum transfer from the piston off the cylinder. So we cut a orange juice container(plastic) in half and filled it with the acid and dropped a piston in(already trashed piston) to see what would happen. O and I was able to clean my cylinder with just muriatic acid and scotchbrite pads, it looks pretty good. Just wondered if any of you knew what it would look like after sitting in muriatic acid.

O yeah and I had PPE, chemical resistant gloves. The bottle had some pretty nasty warning labels so I figured I better use the gloves.

Hello, my name is GreenGoblin and the only thing wrong with that piston is that its from a stihl. That iss why I hate stihls so much. :greenchainsaw:

Since I decided not to get a hone anyone need 3 044 cylinders? I was thinkin about keepin one and dunkin it in the acid to see what happens but if anyone has a hone and needs a cylinder they can have one.

Which models? Are the fins on top "straight across" or are they "diagonal"?

one hell of a serious melt down ?

Naa, it was muriatic acid used to clean up the cylinder. And I'm not sure which they are, I'd have to go look. Does it make a difference which they are(it probably does, just wondering)?

Evan

 

[Lakeside53]

Yes.... use the one with the bigger ports (horizontal fins)

 

[chainsawjunky]

Is it okay if I don't? I'm not sure what the one is that I just fixed today but I'd like to use that once since the others ones need to be honed.

A much better performing saw.... honing is easy...

It's hard without a hone. I'd like to not buy a hone since I'll probably only use it on this saw for now and not plannin on another for awhile(maybe 2 months if I'm lucky:hmm3grin2orange: ) It all depends because I need money for the car in the sig and a honda cb450 motorcycle.
