Nothing past running without a governor and using a 12" pipe nipple for the exhaust.

So an engine will run fine without a govener?

Cool

 

[modelengineer]

Yes, no problems whatsoever.

Lol.

Anywho, I've heard of people boring out the block and placing a .590" Wiseco piston in, then modifying a billet rod and placing that in. Instructions by Mike Clements of Clements Racing...

Did that, got 1/4" popup. Waste of money.

On the other hand, if you could somehow get someone to CNC a 3.5HP connecting rod, all will be well. Mill the head, send the cam to Dyno cams and get it 94SS profiled, then install a Tillotson and loop pipe. Then go to Turk Bros and buy their 3HP Billet flywheel.

how do i go about removing the governer?

 

[lowkhalbalr]

Depends on the engine, your clinton will but IT WILL BE DESTROYING HISTORY. Any engine ran past its specs wont last as long.

Yup, sadly. Start with a $15 block like I did. I somehow worked it up to billet flywheels, billet rods, cams...

how do i go about removing the governer?

Should be under the recoil, be warned about flywheel explosions and rod breakages.

o and what about 5hp cams? will those fit?' or not so much.

Nope. 2/3/3.5 are interchangeable (I've put a 3.5 in a 2), but 5HP will NOT fit. Larger gear.

Hehe, muh 1959 Briggs 2HP, govenor removed, straight pipe, 3HP carburetor....

Its a briggs millions everywhere I have never even SEEN a Clinton(engine or the politician) in person. Coolest flatty I have ever seen is a Wisconsin twin on a BIG generator.

 

[lowkhalbalr]

That's the coolest flatty you've seen? You must mean in person then!

 

[Kenny_McCormic]

Yea in person.

My favorite Flatty was a 5hp Kawasaki that some neighbors sold us. AMAZINGLY BETTER than any B/S I've ever messed with, (probably due to its float-type carb) and if I ever see another pop up- I'm all over it.

I think the 3.5hp motors are pretty cool- I used to be a bit miffed as a teenager, because B/S didn't make the 90000 series engine as a horizontal right off the bat- only as a worm-burner (vertical).
But recently, a friend put one on kart, and it does quite well with us Fat-_sses driving it. (11" wheels/ 5:1 ratio). The best part is- it fits where the 2- 3hp motors do.
