Beware of Suck Back!

[Poley4]

Now I feel like I've been lied to all these years. I was told that that little screen inside the muffler was a spark arrestor, but now I know it is part of the Anti-Suckback-System or ASS.

So his intention for the smaller port is not to create an exit for exhaust gas but to relieve vacuum created by the exhaust gas rushing out the exit orifice?

Oh my that is good stuff, I bet John Force or Kenny Bernstein would just love to pick his brain on that subject.

Actually I wouldn't find it so far fetched that it might be a good thing. Possibly creating some sort of scavenging effect. Something along the effects of why you get better preformence from dual exhaust when you install a balance pipe.

I got my shirt sucked into the muffler and stalled my saw once, I think the location of this port is important. I guess my A.S.S. wasn't working right.

A balance pipe allows equalization between the two pipes because the pulses in each pipe do not happen simultaneously. If we're talking about a single cylinder chainsaw, both exhaust outlets are going to experience a pulse at the same time. I don't see the benefit other than it allows more exhaust outlet area, something a single opening would do fine. Maybe I'm missing something.

How about a 880 with a x pipe and dual Magnaflows? All stainless steel too.

A couple years ago, my wife went way out and bought me the
Stihl insect vacuum attachment. Part # BS4U2
It hooks right onto the muffler.
Used it many times on the deck while having friends over
for adult beverages. (beer). It's on my 088.
Just start it up, ducttape at WOT, flick the suck switch, and leave it run
in the middle of the deck. It's quite the conversation piece too.
What's real fun, is to watch the look on their faces when I try to get the mosquito buzzing around their head. PRICELESS.

My wife (bless her heart), just the other day, for my birthday, in fact,
knew that our house stunk.
So, What did she do ???
Yup, bought the new Stihl Air Purification System. Part #BS4U2
Hooks right on to the muffler. Ducttape at WOT. right in the living room.
It sucks out all airborn allergies right out of the air.
I use it on the 088 for the whole house.
If I'm just doin the babies room, the 032AV will suffice.






NOTE: DON'T TRY THIS AT HOME !!
IT'S ONLY A JOKE.

Thall? You moonlighting?

Can't be THALL...when he dual-ports a muffler, one of the ports is always an exit wound...

He's gonna lay some pipe, then he's gonna try and balance two????????

 

[buzz sawyer]

Yeah, I was gonna say the same thing-it looks like a decent idea, and even maybe well done, but he lost me on the suck back and siphoning parts....

I thought suck back was what the mosquitos did when I sleep on my stomach.

Thats the most useless "modded" muffler I have ever seen. What is that, 1/4 inch outlet? I would guess it would be un-noticeable. The welding was pretty I guess.:hmm3grin2orange:

Your Wife buy those attachments too.

Last summer a Door to Door Stihl Salesman ( said he was from Virginia ).
Sold her the Stihl rotisserie attachment P/N run4it.


Well I thought this is a night to invite the neighbors over.
We had a couple beers in us and was arguing about how much bar-b-Q sauce
on the chicken in the basket. ended up being the whole bottle before all said and done.
Mosquito's started biting so I decided to hook the Stihl bug fogger attachment up at the same time.
Now the Stihl Manual says WOT for the fogger and Idle for the rotisserie, what would you do?
Thats Right, (with the proper deciphering and and the beer making me more wiser, while slapping My last mosquito). WOT it was.
The fog got so thick I could not see anything. All I herd was a bunch of screaming going on. so I turned the saw off.
When the fog settled down, all that was left in the basket was chicken bones.
the meat and sauce was pulled right through the basket. Everybody was covered in sauce and raw chicken meat. ( What a sight ).

The next day My wife called the Door to Door Stihl salesman and wanted to return the attachment.
The salesman said. "Oh NO, Your Husband has gots to Paaaaaaaay".
