First ported saw

[Timdogtrainer]

Also just picked up a ms 460. Very light use but you can barely pull the cord. Something is up for sure. Gotta investigate but it might be a great candidate for a port job depending on what’s wrong with it. Huskyhl do you do any repair work?

I do, but I need to know what’s wrong with it first so I don’t chase issues for days. Hopefully the cylinder is salvageable since used ones are hard to find and new oem is $300

I’m not a Stihl guy but I’d port the 460 before the other 2 mentioned

 

[Lightning Performance]

Yeah and send me pictures of your 441!

Ok

But but you have all day to chase gremlins in tools with issues. Now your a big time shop and all that you love repair work, right?

 

[Timdogtrainer]

I gotta get these saws back together and see what I got.

Any idea what would cause this? It is a cheap aftermarket piston and cylinder

Bad gas detonation or nitro methane experiments.

 

[huskihl]

Old gas

This is the stihl 460 that I bought with toasted top end. Just curious what the heck could cause this. Figured maybe I could learn something. So what do y’all mean by bad gas? Wrong mix, octane, or just old?

 

[Maintenance supervisor]

Old sh¡t gas.

 

[North by Northwest]

Old sh¡t gas.

Yep , old stale gas with a significant octane loss . Preignition or too advanced timing can also contribute to plug electrode & piston crown or ring damage also , however bad fuel is the most likely contributing factor !

 

[Timdogtrainer]

Good to know. Thanks

Man, that is a lot of erosion, whoever was running that saw needs a good hard kick in the nads!

Nitro leaves a dull looking surface. His is too shinny to be nitro imo.

Lol yea I bought a group of 6 saws from these guys. Basically they run it till it explodes and then buy a new one. I’m kinda worried about metal shavings being in crank bearings. Any special way to clean them without completely disassembling saw.

Ah, so they're a hunting club of doctors & lawyers...

No to what? No way to clean it?

Looking to have a saw ported for the first time. I’ve got ms440 and 441. 441 is getting a new cylinder and piston. I’m a casual sawman but use saws a decent amount living on a farm with plenty of fence lines and lots of storms. I don’t have the knowledge or time to attempt this myself. Just trying to decide which saw the port and who should do the work. Looking for a reputable person that may have time lol. I’m located in ga. Thanks in advance.

buy a 460 cylinder for the 441 and do a Hybrid build. Just need someone who know how to shape the outside of the cylinder to find the 441 base.
