Playing With Junk – Building a 4 Cylinder Brigs & Stratton

Here’s a fun project I’ve been following for a while, hoping that they pull it off. These dudes are taking four old Briggs & Stratton engines and making an inline 4 out of them.

I’ve seen other similar builds where they take 4 separate engines and bolt them all together, but on THIS build they are creating one common block, one crankshaft, one cam and flywheel.

I’ve learned a few things, scratched my head on a few others, and got a few dangerous ideas in the process.  It’s fun to follow along and watch where they take this project.

They are up to 24 installments now, and it is nearing completion. It takes a good afternoon or two just to take it all in, so kick back, and open a cold one.

The end result is kinda fantastic!

Enjoy!

    I still can't figure out how they made the crankshaft work.

      Yeah, I'd wished they'd shown the crank too. They also skipped showing it on the twin they did previously. It looks like they just don't have any support through the middle of the shaft. It's just on the ends. No idea how they made the individual crank throws. (The brief shots looked like they were using the original crank throws, and glued them together somehow. I could be horribly wrong about that ;).

      Great find, Pete.

      • I cursed them for keeping it close to their chest as well.

        Evidently the seedy underbelly of the old B&S motor world is a cutthroat place.

          Now I really want one.
