361 carb check valves?

[Greenhorn]

Dropped off my old 361 (6 ish yrs old) at the shop for a carb kit etc. Shop called with a estimate of 350 !!! Said carb cant be rebuilt because junk is inside some internal chk valves that can't be cleaned? Is that legit?

It all started when I ran a mesh air filter instead of flocked, I HATE those things, they shouldn't even sell them down here. They are the only reason I have ever had saw probs.

What's the $350 cover?

 

[Al Smith]

I'm not so sure the saw is even worth that much .

Last 361 (like new) I sold was $375 shipped ($50 in shipping so $325 for saw) to TX. Sounds like somebody is going to get hosed for $350 for carb and labor.

Mesh filter is winter filter for 361 isnt it. Most mesh filters let fines through to inside carb. Wouldnt think you would want mesh down your way.

More info from a stihl tech on filters for 361.

1135 120 1601 Air filter nylon mesh winter

1135 120 1600 Air filter fleece flocked


1601 is a nylon mesh (like panty hose) for winter use. Doesn't keep the crud out as well as the fleece so unless you're cutting in snow, It's not recommended.

I don't have an IPL for that model so I don't know the specific carb model .Never the less it would seem you should be able to buy a brand new carb for maybe a 100 or less .

You gotta remember who your dealing with though because being Stihl you might get sticker shock from the outlandish prices they get .Then too a lot of dealers don't even fool around rebuilding carbs.

Scotts got a couple of used Walbro HD 34b's ,a Walbro HD 34A on flea bay .About 30 a pop for any of them .Even if you have to re kit them you'd have less than 50 bucks in it .

I got a pdf service manual for the 341 361 if you go fixing yourself.

 

[Al Smith]

I can't figure out why a wire mesh filter would screw up a carb .It might play hell with the insides of the saw should it suck in a bunch of dust though .

That saw list a model of the so called "intella " carb. Which from know just a fitting that goes into the air filter and limits the flexation of the main diaphragm should the filter plug up .Hell pull the fitting off and see what that does .

Carb, leaking de comp valve gasket, then all filters, labor. The saw's new version, the 362?, is probably 6-700. I know it still has good compression it always ran way stronger than my 360. I will probably get it back and get a carb and slap on it.

Lesson being - DONT USE MESH FILTERS, unless you are cutting a palm in the snow - lol! tons of fine particulates find their way through fast.

Kinda slow right now, I really dont wanna buy a new saw. Guess I will just use the 441 when the 200 won't hack it for awhile. 361 was so much lighter though and 360 dont have the nuts the 361 did.

 

[Burnham]

I bet you can get by for under $200 if you DIY.

 

[CurSedVoyce]

Less than that B. Carb should be less than $100.00 new from the dealer. Decomp valve aint very much as I recall.

 

[Burnham]

Sounds like under $200 to me, including all the filters .

 

[CurSedVoyce]

Noted.. under $200.00
Man I better brush up on my speed reading.. LOL

 

[Burnham]

Yeah, that comprehension thing gets me from time to time, too .

 

[Greenhorn]

I bet you can get by for under $200 if you DIY.

Agreed, but I barely have time to sharpen chains these days! Carb replacement shouldn't take too long though.

 

[Al Smith]

I just can't comprehend how the carb could get so screwed up .

Now wait a minute here ,idea .Often times itsy bitsy little fibers of wood can pass right though the fuel filter and become lodged in the internal screens of the carbs which most have .If that pot licker becomes plugged it won't run worth a hoot .

It wouldn't take more that 10 minutes to pull that carb off and open it up to see .If I'm right send me a case of Budweiser .

Also... on the 361... flipping the little "summer/winter" shutter on it is a must.

[Bermy]

At what temperature should one flip the 'summer/winter shutter...from summer to winter?

 

[Al Smith]

In your case most likely never . I think the deal is it's supposed to pre heat the combustion air being drawn in through the carb to prevent icing .

Why they came up with this idea I really can't say unless it has something to do with the ethanol content of the gasolines .Which in the form of pure alcohol will indeed ice up a carb and might in fact lend itself somewhat even in blended form .

Way back when there was pure gasoline we really never had a problem in cold air .Quite frankly they ran pretty good using cold compressed air which for all intents contains a slight more oxegen content .You could open up the main jets and lay the fuel to them and the engines purred like a cat .

 

[Bermy]

I'm talking about my other life...it gets cold in Tasmania in the winter...frosty but no snow on the ground.
I've never had to think about the shutter, until now.

 

[Burnham]

I don't recall what's recommended for the 361, but the 200 says change to cold weather at 50 degrees F. Not very cold.

 

[Bermy]

Good to know, thanks!

From what I recollect, the 361 was meant to be switched over long before the snowflake/ ice crystal icon would lead one to believe. It would be confusing if there was an icon of a short sleeve shirt and a picture of a long sleeved shirt.

 

[stig]

All my manuals for the different Stihl models say to switch at 10 degrees celcius ( 50 degrees Fahrenheit for you non metric folks).
