“It’s dead Jim”

I’m still wondering how the bar oil leaked out? Did it melt the cases?

 

271/291 are the same saw different bore. No aftermarket cylinders available. I’m guessing the seals are good since it’s a newer model. Either it had old gas in it or it was tuned too lean and finally gave up the ghost when the weather cooled down

 

Do I need to remove the clutch and sprocket to get the cylinder to separate from the crankcase anyone?

 

Not a mechanic but if the piston is seized solid at top of stroke that would cause problems I imagine. Does it move?

 

Even thinking of burning pine burned your saw up.
That's too bad about the saw. Hopefully you can repair it without too much hassle.

 

I don't know Steals but there isn't a Husky I know of that needs the clutch removed to pull the cylinder. Should have 4 screws holding it down and it should pull up. Carb/intake, muffler and everything else in the way needs to be removed, obviously.

 

Yes

 

Yeah, thats what I thought. Did all that. Got the four bolts removed but it’s not coming apart. I’ll have to take another run at it after I get some time after Christmas. I hope it didn’t do something horrible like weld together…

 

I haven’t worked on a 1 series clammy. But on the 029s and 390’s stuff, the rear bar stud threads into the engine pan

 

Yes take the clutch and sprocket off. It will make it much easier to get the cylinder and the crank out.

 

Definitely take the clutch off if removing the crank, that's a no brainer. Looking for some help, appears to me that you don't need to do all that to just lift the cylinder.


You could just be fighting sealant.

 

Started @ 8:40 to show cylinder coming off. I don't know about this guys methods/advice. Just wanted to show that part of disassembly.

 

I had a bar sprocket get jammed with junk and my saw acted like that. Saw got hot then also.

I had that happen too, but did you see his piston pics through the exhaust port? Mine was literally just a bar tip sprocket jam as well as yours. This one is a bit more drastic.

 

You need to pull the crank out because you will most likely replace the piston. Also, you can replace the cranks seals at the same time.
Taking it, all apart will make it much easier to clean up. Make sure you use sealant that is fuel proof like yamabond.

 

Not sure if the same kit works on the 1 series saws, but bailey’s sells replacement engines for the 029, 290, & 390. You can drop the 390 engine in the 290, same chassis…decent power upgrade for the same money.

 

Finally got it apart. Piston and/or rings had a firm grip on the cylinder wall but got it off. Lookin pretty bad. Can the cylinder be saved?

 

Are the 290 and 291 the same chassis?

 

Never worked on a 291 only on a 290.
