Exhaust help!

[trekklee]

Hi I have a Tecumseh ohh60 and I was think on getting a header but I was thinking about welding on and I need to know where can you buy the header flange so I can weld the pipe on it

 

[mckutzy]

On my build, I just traced the original from the motor(you do have the original right?) on paper. Cut out the trace close to the size you can get, also mark the centers of the stud bolts( im also assuming it has studs in the block, not the screw in type).

Then take the trace and mark on the the steel blank for the flange with a scribe, something sharp ect. (or you could glue it onto the piece aswell).

Cut it out with a hacksaw or the like. set it up for welding.

I can't because the stock exhaust is like flat

i know the first one wont work cause its made of copper and wont weld, the second link said you can weld it to 1" pipe so as long as it fits your engine, go for it. if it works share and if it doesnt share that too.

i didnt check any link besides the first two

EDIT: i just relooked at the first one and the copper one is a similar product. so find one ya like send an email to the seller and ask a few questions.

check this out, it comes with pipe but it has the flange dimensions you need. as long as your engine fits the description it gives

Well trek, why don't you help us help you. Take a pic if you have a hard time describing what your saying.
You didn't answer if you had your original exhaust?

If you are going to build your own, how about using what you got.
Take a piece of paper and trace it on the block if you don't have the factory exhaust.

What the heck does this mean?

Ok, thank you. I do understand now. Also don't take this wrong, I am trying to help as all of us here, we just need more info.

As far as I can see, the area in the pic where the surface mates with the block is the area where you will need to trace out. You will need to have some of the pipe into the block like the stock muffler.
You will need to have shorter bolts as the flange is going to be an 1/8" not like an inch. You'll need to judge that yourself, shim it up with small washers if needed.
You'll most likely need to brace the pipe ahead a bit, mount it to the block or the like, usually I think about a foot from the header.

Now I don't understand here another picture of the mounting holes this is not my muffler but it is similar to mines and same mounting holes

 

[mckutzy]

Post a pic of your block at the exhaust port. Not close up but a clear pic.
What part are you confused about, highlight if nessisary?

 

[DeathStarr89]

this is what your header flange is going to look like...




I'd take a piece of paper, lay it over the port and bolt holes on the muffler.. then lightly rub a pencil across it. The ridges from the bolt holes and the muffler opening should show through.

Then draw the oval shape around it and have a shop make you one.

Also, you should have a gasket between the engine and the muffler, if you do then just take that to the shop and have a flange cut out the same shape.

 

[mckutzy]

What he said, well that's what I said originally. Get a piece of copper flashing, and have that cut out into the shape of the flange, use that for the gasket.

Ok I kinda understand the flange doesn't have to be a oval but the circles have to be right
Am I right??

 

[mckutzy]

Inside's need to match, the outer rim can be for whatever available. Like pictured above.

Ok which metal do I use and weld on and good

Ok this is what I thought of tracing the exhaust holes
I spray something to make it wet on the engine and I put paper and I retrace it with pen

 

[exenos]

That's actually a very good idea! Never thought of it.
