Yea, that's about the price. Believe I paid $280 for my P&C.

The coating on the screen is likely from the additives in the fuel. Just last week I saw the same exact thing in a hedge trimmer. My local dealer, who is in fact quite knowledgeable, insisted the coating was from the fuel additives. The coating was light gray and hard to see until I pulled the screen, it came off in one piece.

That piston has seen better days for sure lol. I think you have the correct diagnosis. Not all of the that is alcohol IMHO, if I were a betting man I'd say that fuel has a bit of moisture in it.

BTW I like the block off plates, good work!!

Yea the block off plates work well. Only had to make the intake side up. The one on the exhaust was made for a Poulan 3400.

Well the 441 is back together and running. The owner decided to give the AM top end from Northwood saw a try. It didnt hurt that someone I respect and trust said they were decent. Without going into detail, the kit did indeed look pretty good, I just spend a few minutes cleaning it up some. It had the OEM Stihl style clips so I used them along with the kits rings. We will see how it turns out.

It got dark on me so I didnt get to try the saw out in any wood yet, I'll try that tomorrow. Even with the limters in place this thing wii 4 stroke hard at anything over about halfway rich on the high side. Got it set about half and its turning 12,750 with plenty of room to go richer yet.

Not sure I like how this thing is put together but it is the first time taking one down and it went back together not too bad. Glad to see all the Husky that was put into this saw, made a decent saw out of it.

I never hardly think about taking pictures when I'm working but here is one with the shiney cyl poking out of it.

Looks good! Did you ever figure out how all of that crap got in there? Do this guy run his own saws, or does he have a crew?

 

[Modifiedmark]

No I didnt find out for sure. I did check it close and found no good reason for it to look like that. The filter is undamaged and fits well. I'm thinking that as others pointed out, it might have come loose before and it will be watched closely in the future.

If thats the case it will be addressed.

I'm actually looking forward to running this thing tomorrow. I had run it before and thought it was a good running saw.

This is a father/son tree service with some help now and then from a climber and a occaisonal other helper. Not a big time outfit.

Good deal mark. The AM kits are what they are, and the so far the one's from Northwood look better than most I've seen. Anyway glad she's up and running. I've found that strato saws really don't like to be ran super rich, they seem to load up in the cut and won't make any power, so keep that in mind when tuning.

Overall the 441 is a good saw, just somewhat of a goofy carb box with all the lines going through it. Trust me when I say the 362 and 261 are both an improvement over the 441.

Let us know how she runs.

Yeah Andy this kit looked ok, better then what was going on in that "other" thread about the AM kits.

Never fear, I also have found that the stratos dont like to be real rich as well. I'll find out tomorrow how it runs.

 

[DarthTater]

Long time Lurker who just Registered to see the photos on this.

I've Never seen that much gunk in a carb, not even on a pice of junk Homelite weedeater I have that dosn't have a filter or any way you can add one.

Jeez!:jawdrop:

Well now this sucks, didnt get through one whole cut with it.....

I'll make the phone call in the morning...

Wait it gets better, the owner called as I was taking this apart again, said he's bringing over his MS460 for me to look at to see if I could fix it.

This is what he brought in. Now he needs the 441 bad.

I wonder if there are any 460s left at the dealers?

 

[Ductape]

Ouchie !

 

[Modifiedmark]

Ouchie !

Yeah, which one you talking about?

 

[LowVolt]

Damn that sucks! What happened?

 

[ford832]

Well I wont argue about the filter but it was really not that dirty when I took it off. No matter though, that dust didn't melt it down and kill it.

The one I rebuilt lunched itself like that,and the filter was tight(at the time anyway), the carb throat was stogged full of dust and the limiter caps were on,and adjusted to the rich side.I think I'd grease them too,it seems to be a common theme.

Damn that sucks! What happened?

It hooked a ring on the exh port.

Glad it happend now, not later.

 

[greg409]

Looks like the wrist pin clip came out? (with these old eyes it looks like the pin-hole edge is cracked off)

Ten deep breaths


luck,greg

Didn't make the whole cut through a 24" log.

 

[jbighump]

im sure northwood saw will make this good they have great cs...

 

[XSKIER]

That'll happen when you put the piston in backwards. Always remember ring locating pins toward the intake side. Thanks for sharing, I don't think I'd have admitted it.
