MS460 Teardown-Comments Welcome

1) Why would they go "lean" to compensate for an air leak?

Well you never know what the prior owner did. Maybe they turned it richer and it didn't change much then they went leaner? Who knows when and why they turned the screws. I never trust the settings on a saw of unknown history regardless of the age or condition. A pressure and vac test is very quick and simple especially when you have the saw partially torn down. It would rule out any issue of an air leak when you go to fire it up. Glad it's running well for you. They all won't be like that!

Jeremy,

The plastic carb cover on the 440 just has a extension that plugs the snorkel on the carb. My newer 044 has the same plastic, even thought that saw came w/o a snorkel carb. On the 460, the snorkel passes through to the air filter.

Is there a reason they wanted the snorkel on the 460s but not on the 440s? Or do some 440s pass it through like a 460?

 

[MustangMike]

Dan, I was pretty confident that the carb adjustment was the problem, and paid close attention to how the saw reacted when I started it up. If there was any kind of a leak, I would have shut it down quickly and tested it.

I'm sure I will have to unpack that tester and learn how to use it some day!

All the 044's/440's I've seen, need the snorkel to pass through into the filter base. This is what STIHL calls "Intellicarb".
If that snorkel becomes blocked in any way, the saw will not run.....but poorly if so.
It's the atmospheric vent for the carb.

Sounds like you have a hodgepodge of parts Mike

A light bar would help but I put a 28 on my 46 and never even tried to use it.

In the woods you better set the break before you set it down cause it goes straight on its nose and I hate that.

395 with a 36" still sits up.
Role around like a ball in the bed of a truck though,damn husky

That's what they need: a kickstand.

Stock 394/5 will hold 10.5k with full comp on a 130 dl bar in red oak

130 .375" or .404"?

Jeremy, I will take some pics, but I don't think that statement is accurate.

 

[MustangMike]

So, I was at the local Stihl dealers today, and I requested a 24" plastic scabbard for my saw. The guy looked, and looked and looked and told me they did not have any, but he could order me one. I told him I wanted one today, and asked if he had a 20" one. He replied, no, the closest he had was a 25"!!!! I told him I would take it! Folks, I don't make this stuff up!!!

OK, I owe Jeremy 1/2 of an apology!

Here are the pics, from left to right:

1) The old 044 (SN 120...) does not have any provision for intellicarb.

2) 044 SN 126... (a red lever saw) has a provision to block the intellicarb snorkel.

3) I mistakenly thought the 440 was the same as the newer 044, but it is open where it goes into the intellicarb. However, I think you can run an intellicarb on the newer 044 and it will run just fine with the snorkel blocked.

I believe all three saws are "original" and I know for a fact that the red lever saw is, I have owned it since new.

If the saw originally had a non HD filter, it would not have the snorkel

Looks like you're 50% short to me.

 

[MustangMike]

I don't think they had intellicarb when the 120 saw was produced, and the 126 saw came with a 3 layer filter, foam, pleaded material, foam. Looked pretty heavy duty to me!

And your proof is???

 

[hseII]

And your proof is???

You based your 1 piece of solid evidence off a saw that was sold before the intelecarb was the norm?

Or,
HD filters from OEM.

 

[Redfin]

I can't imagine running something stronger than the 661 I've got here, but I'm willing to explore a little

Just a little?

The proof, one way or the other, will be when I put a intellicarb on the 126 044 and see if it runs OK. If someone else has tried it and knows if it works or not, please let us know and I won't bother, but as of now I consider if unresolved.

Well thank you!

Yup, just a little............. You got something devious in mind ?
