Flathead B&S carbs and tanks are getting scarce. Does anyone make an adapter to install a 5HP Tecumseh carb to a B&S? I could make one myself but I'd rather buy something nice.

The only one I know of for a tec float carburetor is 691922 and after buying it a float bowl carburetor and making a throttle you might be $80 into a carburetor swap. IF YOUR BLOCK IS NOT A THREE BOLT HOLE INTAKE BLOCK DO NOT BUY THIS

What he said ⬆️. Tecumseh plastic fuel tank, the kind with a red cap. The screws do not penetrate through the top of the tank, they have “blind holes” molded there, FYI.
For example:


Tecumseh 35584
Tecumseh 36247

I love this intake. It's like an Edelbrock for a B&S. Amazing. However, looking at the Tecumseh carbs, it's likely that I'll have to cut a notch in the side cover for the fuel inlet hose, as the intake positions the carb immediately beside the cover.

I’m stating the obvious for many, but Tecumseh ran the fuel hose across the front of the engine under the blower shroud, which seems “wrong“ but at least it has a fresh supply of forced air at all times.

Would love to see a photo of it installed.

I have never used a tecumseh carburetor with this intake I have only ever used the Tillotsons.

Really do hope it works for you and you can get the line hooked up. If it goes through a hole drilled in the metal shroud make the hole a bit oversize and run the fuel line through a rubber grommet.

The fuel line is clipped to the block under the shroud and right next to the spinning flywheel on tecumseh engines standard.

Next question is your tec carburetor is fully adjustable right? idle/high side mixture screws?

I don't have a carb yet. What about the Tillotson?

I’m sure your figuring out any carb that isn’t the stock tank carburetor will need it’s own throttle cable and gas tank.

The Tillotson is ran from a fuel pump so I just run an external tank mounted anywhere I want it.

You will need the tools to make a washer for The throttle cable.


Any setup that is not stock takes a lot of doing to make work. The china Tillotsons are not worth buying and the real used Tillotsons from stilhl engines will need a rebuild kit but they work very very well.

I would look on eBay for tec H40 carburetor they are fully adjustable. you can either dent the ever living heck out of the shroud or drill a hole in it to run the fuel line.

pictured below is a tilly (Tillotson)
