Been doin a few port jobs here and there to supplement the income and share the wealth with the Irish. Today, I did a muff job on an MS261C-M and it freaking scared me. This is after about 2 hours of work or so fiddling with the muffler to remove the internal baffle(which is a pain to reach and is almost hidden). I thought this thing was loud when I got it, now it's distorting the camera at the end of the vid:



That's a 6-7 second difference. It is exactly the 6th cut I did after I reset it having done the MM.
 
after the first or maybe the second time I squirshed my little 260 I decided to hack it with the ole dremel, even my limited porting skills made a world of difference. I'm currently looking for a back up to this one as its starting to show signs of fatigue from all the abuse I've given it over the years...
 
Here's the reason this one is particularly strong:

Nearly 190 PSI. You can really hear it in the exhaust, it's very stoccato.
 
SPeaking of painful - the reason the vent is leaking is the cover pushes against it when I lock her down without a gasket...

For want of a nail...

Oh, and this happened:



Psst... that's semi chisel chain, to boot ;)
 
If you lean on her, she just loads up on the chips. The times for the mods are:

Stock : 23 Seconds in that wood(Horse Chestnut - about like Big Leaf Maple).
Mff Mod: 16 seconds (with the baffle nearly completely removed)
Conservatively ported: 13 seconds(but she has a load more torque and throttle response is instant).
She steadily grew louder and louder. This saw starts life loud, but she piles on the dB once you remove the baffle.

 
tank vent pn 0000 350 5800
O-ring 10x2.1
Then some had this rubber flapper inside the tank. 1110 353 1600

All I see in this thing is the sintered cone cap and the rubber vent thing similar to 1110 353 1600, but black, and under the cone. I'll replace it with a flapper in the tank and see how she does? Nothing in it that looks like this:

It looks liek this, minus that orange part. It has a black thing similar to it that pokes down into the tank and has a tiny hole in it to vent:

you have the first/early style that uses the rubber flapper. 1110 353 1600
 
OK, dawg, I gots another question. Got a guy here who has a 362, the main spring where the handle meets the front of the chassis is weak. Is there a strong full wrap version ya got a part # for?
 
Sorry, I only have ipl's for a few of the older Stihl saws I used. The 362 is too new for loose copies of ipl's it seems.
Some searching didn't lead me any where either.

I can attest with experience that those are a b!$%@ to suck through the hole. If I remember right I ruined the first one and had to get second. Hours of screwing around to get it in.
 
Too bad the phone takes crap pics. That oak is maybe 60" DBH. It died last year, so is the perfect firewood candidate.
