Super Bronc Muffler

[dozerash]

Anyone know where I could find a Super Bronc can muffler?
Looks like a Nelson muffler. Also saw something similar to it in the Tecumseh HM100 parts catalog for muffler options. Bike in the picture has the muffler style I’m looking for. Thanks

Have you checked EBay? Try searching "Nelson mufflers" I found a used one very similar for an old garden tractor late last year.

Can someone please give me the measurements of the Nelson muffler? Diameter, width and size of inlet/outlet? Thanks

 

[dozerash]

Someone gave me the dimensions for the Super Bronc Nelson muffler. They all have the number T-11892 stamped on them. I’ve searched that and come up with nothing. Now if I could find one with at least the same diameter, I could modify it to work. Found a few similar on eBay but usually larger diameter. Someone said Simplicity might have used that muffler.

I found this Nelson muffler on eBay, that might work for my Super Bronc. It’s not the same but the can part seems to be the same size. I’m thinking I could put an elbow on the outlet and route it down. Not sure if an elbow would restrict exhaust flow enough to worry about, or if it would be a leg burn hazard. Or I could weld a cap over the end and drill/weld an outlet like the stock one? I have a piece of steel that will work for a mount. Just need to cut and drill. I just need to find 1” flex pipe and big enough hose clamps. I just mocked it up on my bike with magnets. The little bracket is going to get removed.

@dozerash the super bronc also used a beautiful flat Taylor muffler. Perhaps there are some of them out there.

I'll try to find an example picture.

Here's my super bronc. Zoom in on the rear fender to see the flat version taylor.

Maybe this helps.

I bought mine from Rick Chatten @chatten63

Looks like a muffler you can get for an old gravely and Briggs I had one on my 816s Gravely. Look for Richard’s Lawn mowers in Spencer WV

You from Spencer are you?

 

[JoePaint]

Nope Pittsburgh, hut dealt with Richard’s with my Gravely. They were super good with customer service. I would send a picture of exactly what you need with sizes and see if they have it. Just a suggestion as all this older stuff is harder to find

I thought the Taylor muffler was even harder to find? Looks great though! Was it expensive?

Not bad, I bought it from Rick, about 8 years ago, for $100.

Have you reached out to Rick ? @chatten63

He always knows about super bronc parts.

That’s not a bad price. I know Rick said he didn’t have the Nelson muffler.
I was looking for something else on my Tecumseh microfiche and found the Taylor muffler there. It just said it was a 800 series. I didn’t see a the part number for it. Not sure if it’s the same one but it looked like it. I did find the part number for the adapter that mounts to the engine to use the flex pipe, Tecumseh part # 391012 for the HM80.

Does anyone have a copy of the accessory drawings for the spark arrestor for the Super Bronc? Taylor and or Nelson? Thanks

@dozerash , my friend @Mariah that built my bike, improvised a bracket to attach the muffler to the rear fender attachment cross member.

To me, it looks like a piece of quarter inch flat steel, drilled at the proper spots, running forward of the fender bracket, space offset from the fender bracket with a circular piece of hard nylon stock.

Here's some pictures:
