Sold Stihl ms 260 pro

[mtlogdog]

I have 2 saws for sale both saws are woods ported run great asking $375 for 260 + shipping .325 chain
$ 325 for 026 it's the 44 mm saw with metal handle fresh rebuild + shipping .325 chain on hold till I get a new carb for saw

 

[mtlogdog]

The 260 had 160psi the 026 had 145psi I couldn't get a good pic of the 026 cause my gauge started to bleed air before I could take a pic I live at 4500 elevation so comp is higher I just don't know how much

 

[gunnusmc03]

Isn't it the other way around? If you live at a higher elevation isn't the air is usually thinner?

Who ported these?

 

[mtlogdog]

No cause at sea level it's 14.7 psi and the higher you go it gradually becomes less psi I'm sure there is a thread on AS that covers this. They were ported by me like all my saws are I went to school for porting car engines then found this site 2010 and been doing it ever since I opened up the intake and ex on both saws lowered the lower transfers a little cleaned the windows on the pistons did not remove much material from them so not to make the brace where the wrist pin weak

I did some research psi at my altitude is 12.5 psi which is a 1.176 difference I did the multiplication and these are the #s I came up with. so this means at sea level the 260 would have 188 psi and the 026 would have 170 psi. The 260 is broken in with a couple of tanks ran through it the 026 only been tuned and is not broken in at all

It appears that compression should read lower as elevation increases. Here's the link to a thread about altitude and compression variation. Standard atmospheric pressure at sea level is 29.92 inches of mercury. This changes by approximately one inch of mercury per 1000 feet of increased elevation. http://www.arboristsite.com/community/index.php?threads/Altitude-and-Compression-Testing.82993/

Nice saws BTW...

I read warpig6 post wrong and posted a dum reply my fault

 

[warpig6]

It seems you read my reply wrong. I'm agreeing with you...

 

[SCTREEGUY]

You both are saying the same thing just looking at it differently.

 

[warpig6]

Hey mtlogdog , Let's see some pictures of the port work. Surely somebody needs a nice 49/50 cc ported pro saw.

Unless you cut the base on the cylinder, either the math isn't right or the initial readings aren't right. 026/260's are more like 160psi near sea level (I'm less than 100' above sea level) and I've been inside quite a few of this series.

Or possibly just removed base gasket, I would be interested in the 026 but my better half is really giving me some dirty looks right now about buying another saw! Lol

I know nmurph has forgotten more about saws than I know but my 026 with a base gasket delete has some pretty stout compression. It's a REALLY LOW HOUR SAW. I split the case (somebody else already started) and didn't replace bearings, seals or rings. I was expecting to find the compression near 190 which it was last year with about zero run time. I just checked it and got 210. I then had to check a Husky 359 that's base gasket delete and got 175 which is about what I was expecting. My gauge is an OTC that's about a year old and has been fairly accurate.

 

[mtlogdog]

Yes both saws have the gasket delete I did read post wrong my fault I don't have any pics of the port job I get too excited when I finish porting and reassemble the saws the 260 is all oem never been blown up the 026 had a bad piston I removed transfer from cylinder walls and replaced piston it is AM

 

[mtlogdog]

Here is a video of the 260

Having problems with the 026 gonna get a new carb with high low adjusting screws then put back up for sale

 

[kyle.kipple]

Is the screw missing for the brake handle on the starter cover?
