Husky 61

donbj · April 25, 2021, 02:36:04 PM

Aquired this 61 and it has this weird attachment on the muffler. It doesn't look scabbed on but who knows. Any ideas as to what this could possibly be? It's a hollow pipe and runs to the bottom of the clutch cover. Hmmmm.

Someone also trimmed the hood a lot. You can see the hand braze job.. Its a backyard thing.

I dunno if its sposta be a bar oil heater or a sawdust blower outer or trying to direct gas away from the trunk? Looks like the original gill vents on the side are shrouded too. None of my 61s had that big shroud bracket redirecting gas that way.

Maybe for their version of a Nordfeller. You can Google some Nordfeller setups for the 70E. Kind of a real rare beast in NA. I've only seen a few ever.....complete

Not factory(the pic) as far as I know.

Didn't think it was a factory thing. Whoever did it did a good job. I can't think of any gains in this. I don't think it's chain oil heat as it doesn't go near that.

The thing fired up so we'll ponder and go from there

Real1shepherd · April 26, 2021, 05:02:55 PM

We may never know on that guy, unless someone else has seen something similar. Personally, I don't see any advantage of it?!

How does the piping end....does it have threads?

Not for a Nordfeller, they tapped the pressure from the combustion chamber.
I too have seen only one, for a Jonsereds 451.
I wonder if it is for killing moles

The piping just ends at the bottom of the clutch cover. Probably someones idea of a good idea :D

May have been an attempt to blow 'curls' clear of the side cover when noodling.

mike_belben · April 26, 2021, 09:37:53 PM

are the muffler gills closed up? is that pipe the only exhaust passage?

Yeah, I know that....I said "their version". I've seen 70E's completely set up for a Nordfeller. And I saw a vid once of one all hooked up and demonstrated. Doubtless I'll ever see one in the flesh. Can't say though that I feel I'm missing something in life.8)

Noodling happens mostly up inside the clutch cover.....not thinking this would help much for that.

DHansen · April 26, 2021, 11:14:36 PM

Looking at the two photos and the two modifications, I think someone was attempting to remove heat from that area of the saw. The modified top cover would allow heat to rise off the muffler. The pipe would have routed hot exhaust gases to to side opposite the operators left hand and low. So why move the heat off to that side? Does the top cover help with air flow across the head?

The muffler exhausr openings aren't restricted at all. I put my hand under the pipe end and couldn't really feel anything when it's running. Pipe isn't restricted either. May just be one of life's mysteries as to motive/intent here.

I do realize that :D Just throwing something out there that the inventor may have been thinking

mike_belben · April 27, 2021, 02:40:01 PM

yeah im chalkin it up to some kinda wonky fail idea.

leeroyjd · April 27, 2021, 03:23:51 PM

Maybe for an Alaskan mill ?

Spike60 · April 28, 2021, 05:30:48 AM

If we don't get some rain around here, that would be a good way to start fires.

Good ideas...customizing...usually catch on if repeatable. Sometimes though, there's no real gain, except in your head.

I admit, I'm baffled by this one. I can usually see where someone is going with a mod, but this one escapes me.

BradMarks · April 28, 2021, 12:23:41 PM

Used to own a couple 61's, may still have a powerhead somewhere. Always wore White-Ox cotton gloves. I remember on really cold wet days it felt awfully good to put my gloved hand on the muffler for a bit. Not too long as it got hot. Perhaps this is an adaptation of that?

Real1shepherd · April 28, 2021, 01:46:31 PM

That's the best theory yet.....a hand warmer for cold/wet weather conditions!

A poor man's version of heated wrap handles......

mike_belben · April 30, 2021, 05:56:12 AM

Maybe its to keep the coi pond warm on those frigid february nights.

The hood on those fits really really tight to the muffler and the front edge often melts on white hoods. Obviously someone felt they had a heat issue. Probably just lean.

The tube may well be for gassing vermin.

DHansen · April 30, 2021, 08:41:11 AM

Use the saw a few times and see what affect the tube has. Just might help shine some light on to this subject. That tube is moving exhaust gas to a new location, but why and how effective is it?

BradMarks · April 30, 2021, 04:34:03 PM

My experience says the front edge of the "hood" always melts

DHansen · May 15, 2021, 08:29:22 AM

Have you cut with this saw yet to see what affects the pipe has?

Haven't done anything with it since the discussion here. Got real busy with other things and haven't had time for much of the fun stuff >:(
Oh well everything in its season! My neighbour saw this on an auction site and said he thought of me when he saw it and put a bid in and got it. $20. Packed it around for two months in the back of his truck as he worked out of province and gave it to me when he came home. Very cool machine! No clue whether it ran or not or if it even turned over. We put it on the benched and checked for spark, nice hot blue. Decent compression. Hey lets put some fuel down the carb bore and crank. Darn thing fired up! Fuel lines are rotted off and it looked like it has been sitting in a barn for 50 years. But it all works. Gotta find a blade for it as this one is broke but should be able to find one. Cool late 50's Wright Saw reciprocating saw.
