What in the world is this???!!! MS661 related.

Shawn Ray tore one down in Canada to send me the jug.......same thing in the intake.

He asked me what it was......I had no idea.

I've ported a least a dozen of these. I've yet to see that in one. Really weird.....

Amazing. So this isn't the first instance. Sounds like they need to tighten up on QC a little bit.

I'd have to agree.

I've been known to give Husqvarna grief over their lack of QC........looks like it's Stihls turn to take some heat.

 

[RedFir Down]

I thought only Husqvarna only had this stuff happen.

Hey it could be worse - like if the cylinder plating failed.

 

[pantelis]

Lets waiting to see what the stihl tell for this.

Maybe this is a restrictor plate, kind of like in NASCAR, lol.

 

[pantelis]

smell something

Does it look like they could come loose, and be ingested?

If any saw needs a restrictor plate.......it's the 395XP.

We dont need no dang restrictor plate !

Maybe its a new fangled reed valve.

It might be good to compare the serial number and date of build between Shaun Ray's saw and the one you're working on. There might be a whole batch of saws with those things in them.

I think they're too big to move any farther. They're kind of folded and sideways in the bellows area.

 

[Gypo Logger]

A conspiracy, Its an inside job!

 

[milkman]

Just somebody at Stihl that has been reading about Treemonkeys JB Weld and trying to improve on it.

 

[Gypo Logger]

Its either a calk ring or a rolled up condominium.

Good idea.

Klotz R50 actually burns pretty clean, I ran it for years @ 32:1 and never saw buildup like that.

I have ran several tanks @ 32:1 through different applications, and R50 actually helped clean the tops of the pistons.
Bikes, blowers, weedwacker, and saws .............. havent seen much of any buildup
I am running VP94 exclusively though

 

[Mastermind]

R50 is pretty clean stuff.......Super Techniplate on the other hand is nasty.

 

[singinwoodwackr]

would running premium gas rather than regular make a difference in deposits?
Klotz Super Techniplate at 32:1 I've been running this in all my saws for a couple years now and never seen anything like this buildup.
So, which of the above suggested synthetics should I go to? price/gal seems about the same with freight via Amazon.
the mystery continues...
