I have a muffler like that. Acquired it in my misguided attempt to find one for a 670. Bolt spacing was just a touch wider on the 630/670.

Offer it here for postage.

Also have a couple 630/670 mufflers. Gutted, no deflector.

Ended up with a cheap aftermarket with tube outlet. Works fine. Don't fry brake handle no more.


Darn, didn't count on the stupid tag.

Check out the extra support arm under the muffler. I did try to fit it to a 90 but the spacing didn't line up. Fits fine on my 621.

The muffler bolts are longer because of the extra shield. Anyone know why there were two different options?

Dean do you mean two different muffler options or two different cover/shield options?

May be a spell till I get on my 'puter. This phone don't do PM that I've discovered.

Yeah, 630 with a divot on the tag makes it look like a seven. Ass hat seller.

Ahh.... I was just responding to your offer on the 621 muffler....

Ah Ha, that's what it is. I was never certain. Got it from another evilbay ass hat seller who 'thought' it was 630/670.

Text or call the number on card below.


I got cards for Christmas.[emoji4]

Husky had different mufflers even on the same model/2100. Even had one called the "jungle muffler" which is pretty rare. I think a lot of it has to do with regional requirements. All the pro saws had shield plates and spark arrestors that I bought. The Forest Service would periodically come around and check our spark arrestors and to see if you were carrying a proper fire extinguisher. Even firewood cutters would have to meet those requirements up in the National Forest or BLM land, although with them, it was harder to enforce and find them. Enforcement officers would just walk onto the loggin' site.

You better make sure I don't know WTH thing fits.

 

[67L36Driver]

Why I wrote 451E on there, I can't remember.

That muffler looks a little different tan mine. It doesn't have the case leg on it.

Two different muffle options. Was it a regional thing?

Yes that fits a 451E, 49sp, 52/52E etc.

Actually there were 3 types...the regular exhaust exit with just a square hole.....then the two spark arresting mufflers.....the top louvered one like yours with a large ss screen behind the louvers, which is the later type......and the early spark arrestors which had a large hole where the square hole is on the regular ones...the hole is threaded inside to accept a threaded brass ring to which a fairly long ss cone shaped screen was attached....the ring had two hole which took a special spanner to remove and install.....here is a pi of the 49sp version without the screen or ring......and one of my 70E with the top louvered muffler....

 

[Cantdog]

The only regional muffler I can think of is what they sometimes call the "West Coast" muffler which was very open on all models and exhausted out the lower half of the front through a larger ss louver or a steel louver on later models like the 9XX series........

I don't seem to have pics of either..the early or late......I do have these mufflers at the shop and will try to get some pics.....

All that said there may well be more spark arresting mufflers out west than in the east due to early and strict federal regs for cutting on BLM and national forest lands but you could order them either way in the east but were generally sold with the square hole mufflers in the 70's.....

Here's the exhaust that Robin is talking about....used to be an arrestor screen behind the louver...loooooong ago burned out. I'm not fighting with the Forest Service anymore, they can come find me....lol.

That stuff that looks like something my saw puked outa the exhaust was my brief run with Amsoil gas mix at 50:1. Don't use their product unless you want to risk 100:1...which I feel is foolish on a larger cc saw...I don't care what they claim and it sure as hell didn't work @50:1 except to make a BIG mess....grrr

.....had a large hole where the square hole is on the regular ones...the hole is threaded inside to accept a threaded brass ring to which a fairly long ss cone shaped screen was attached....the ring had two hole which took a special spanner to remove and install

Exactly how Husky did it on all the 2100's I bought from Baileys....still have the spanner tool. In the pic, you see the deflector hood which can point in any number of directions and if you look closely, you can see the slats for the screw-in spark arrestor. Tool is second from the left in the other pic. How J'red might have done the screw-in arrestor could be a tad different as far as the tool goes. but the same principle.

The 621 is ALIVE!!!

Finally got it running consistently yesterday after a carb rebuild. Probably still needs a little tweeking but I got it to idle great!!!!!

The only bar I have is a tiny 16" windsor, it needs something better than that.

 

[Real1shepherd]

One way to test your carb kit job is to turn the saw on the side....like you're making your first fallin' cut...on a Tilly carb, the idle should only decrease a tiny bit.....shouldn't stall out.

Lol...that bar's an insult to the saw. You gotta cough up the $10-$14 @SawAgain for the pull handle...I think most of the old J'reds used the same pull handle.

Nice lookin' saw for a little feller! Repaint the top and the saw would look new. I don't know what kinda silver would match and hold up....whatever J'red used didn't seem to hold up, but the red sure does.
