will a ms 261 cylinder kit work on a ms 271 with a 3 bolt intake

[Joe 025]

I just got this saw today (E bay Special) I'm guessing it's a older one with the 3 bolt intake Can I use a MS 261 Cylinder kit on this? thank you

No, the 271 is a clamshell, while the 261 is not. You options for a top end are the 271 and 291 only.

 

[Joe 025]

Thank you was hoping seem to be having a time finding a top end rebuild kit or OEM.

And, you are right about needing to match bolt- versus clamp-on era parts.

I believe, the older saws are easier to find AM parts for.

I looking for this hyway kit now H30271 this is the one for the bolt on intake no luck so far, but enjoying the hunt.

 

[irhunter]

I suggest:

1. Don't split the motor until you have pressure/vac tested it. Only then will you know what caused the problem.

2. Don't order parts until you have split the motor and cleaned up any cylinder damage. Only then will you know what parts you really need.

Thanks Roy I understand pulling the jug this afternoon with luck the cylinder will work after a good cleaning..................hoping.

 

[Joe 025]

Piston is toast from pulling the muffler

 

[irhunter]

Good luck!

I have had a new-style MS291 all apart for over a year...waiting for more AM piston options to come available.

 

[Joe 025]

Have you looked into Hyway and Meteor they have a nice pop up piston

 

[irhunter]

Those two are what I'm waiting for. Neither makes pistons for the new-style MS291.

I suspect, they both will eventually.

I could buy LRB right now...but, would rather wait. Just personal preference.

 

[Joe 025]

Yes I can see that good luck on the hunt

 

[Joe 025]

Looks I'll be able to save the cylinder at this point just a little transfer on it that I think will sand out.

 

[Joe 025]

I wonder if anyone has converted an older style 271 to the newer style seems all you would have to do is buy a new clamp on boot...................never that easy right?

 

[irhunter]

I don't have the new-style IPL, but, clearly, there is a piston difference between old and new saws.

I have never read what it would take to convert forward or backward. I am not sure the repair/modification of these saws attract a lot of...engineering talent.

I plan to wait for Hyway to sell a new-style piston, buy one, install it, and then sell my 291.

No. I did one a couple of years back so my memory of what all was involved is not so good.
But, more or less, you buy the cylinder and the intake boot doesn't fit. So, you buy the new intake. Then the housing piece or whatever you call it that creates the baffle around the carb doesn't fit. And, so on.

Kinda what I though,

the older one takes the same piston as the the 261

If that is the case it is likely that you can clean your cylinder up plenty well enough. Unless, it has broke a circlip or something and made a deep gouge.

I got the cylinder nice and smooth and ordered a hyway popup piston for the saw, we will see what happens. I'm sure it will blowup as I have never replaced one before but no guts no glory.
