$9 echo at goodwill. Why lol

I knew better. But I bought it.
It's all kinda rusty. Not the typical Arizona thing. Probably was submerged for a extended period. Engine is seized.
I poured some mineral spirits into the spark plug hole. Will let it sit a while. Then Probably tear it completely apart.
I've not bought a saw in years lol.
Hopefully I don't start buying saws again lol. I went from cad to gas (guitar addiction syndrome) and ham radio hoarding.
I still have my stihl 038 mag I rebuilt a few years back on here and my dcs6460 home depot saw and my old dolmar and the baby ms210? I forget. And a xturd 372. We removed a giant. Elm tree stump in the backyard. That was the last time I used a saw. Out there huffing and puffing with rona virus working that crap out of my system for the second time. Cutting x in stump haha.
This is such a cute little saw. I had to try n save it.

That rust on the spark plug is not a good sign. The crank could look pretty ugly

 

[ballisticdoughnut]

I see your a glutton for punishment.

I'm sure it's screwed. Did you see the chain? It's like it was in a bucket of water lol. The muffler is rusty. It's a shame I need a smaller saw. I know these aren't a popular saw on here but I've got plenty of big saws that I never use.

Well I was born in Washington state, what can I say lol. Skagit county haha

For less than $10- you got yourself a whole lot of fun.
Sure the rings are probably stuck to the cylinder, sure the bearings are probably rusted solid, but you will have hours of entertainment finding out.

 

[Thommo]

I would try to salvage the chain. It might only need a good soaking in WD40. The bearing on the bar tip might be a problem if it is pitted from rust

 

[Philbert]

Worth it for parts. Find someone with a similar saw if rebuilding does not feel attractive.

They’re nothing amazing but I’ve never heard anyone bad mouth a 400. At the very worst buy a new 400 for cheap and now you have a pile of parts for it

 

[singinwoodwackr]

Soak the entire thing in Seafoam; I hear it’s miraculous, lol

 

[August76]

I will let it sit a while. When I get bored I'll tear it down

Just remember they only RRP at $299 brand spanking new, soak it up, knock it about a bit to free stuff up, flush it out and run it.

If it was mine I'd block off the exhaust and intake like I was gonna do a vac/pressure test and fill the engine through the sparkplug hole with some older 2 stroke mix that I wasn't using and let it sit awhile. If it has an impulse hose you'll have to block it off too. Maybe it will unstick itself..

I have poured mineral spirits in it. Been sitting a few days. Down plug hole and carb. I thought about smacking piston down with a large punch

I would wait a bit longer then just try to turn the flywheel, it might break loose..

 

[August76]

It took some careful doing to not snap muffler bolts. But I got it. Ring looks OK. Piston looks ok. Hmmm

 

[Woodslasher]

Now would be a great time to scrape out the carbon and gut the muffler, fyi.

 

[Philbert]

‘Smacking’ the piston sounds like putting a hole in the top.

Years back, a member posted that he brazed a zerk fitting to an old spark plug base, and used a grease gun to apply pressure to a stuck piston Only works if piston is above exhaust port.

I thought about it and decided that it was a bad idea.

Using a wooden dowel and smaller hammer can dislodge it enough to break initial seal and let your oil work around the rings.
Not such a flash idea if using a steel punch, the piston is at TDC or BDC and or the crank bearings are frozen completely solid.
But for a $9 investment- not a lot to loose.
