The de facto standard for this hobby is a shaft that's 3/4" diameter and about 2 1/2" long in order to mount centrifugal clutches or a torque converter (TAV), although there are ($$$) options if you have a 1" diameter shaft.

All these small engine carburetors eventually get ruined by neglect, water in the fuel, by stale fuel residues and by ethanol in the gasoline which draws moisture out of the air and contaminates the fuel over time.

I have cleaned more than a few carbs that were otherwise junk. Rewarding work.

Depends.

The solid state Magnetron armature is a bolt-on, no fuss upgrade but the points are kinda fun. I honestly have no idea what the service interval is for a Briggs with points. Especially if it gets a lot of use.

Maybe McKutzy knows.

It's definitely an extra maintenance concern.

Heh, I had what I think was a 3HP armature with one of those clipped on. I thought it was factory though, like an intermediate example. They were phasing out the points and switching over all ignition to the Magnetron about 1981 or 82.

That clip on thing might have been a way to use up existing stocks of the points coils.

See if you can find that cheaper elsewhere, or just buy the Briggs 397358.

As far as I know.... Its pretty easy to use the converter module, and you just unplug the condenser and rout the wire to a convenient place...
On page 30, i found the spec for the breaker....
https://docs.google.com/file/d/0B6Na...NaTzlpWmc/edit

Its in the resource area...

Do you guys know if there is a commercially made intake to put a 22mm mikuni on these engines?

Mostly for the Animal and LO206 engines (both very similar).

To my knowledge, no.

Plenty of people have done it though by fabricating a custom intake manifold from steel tubing and large washers or flanges (plate steel). I'd love an aluminum one though.

Here's a setup designed to fit the Animal carburetor...

Not enough info there.

EDIT: Jinx. Kartorbust and I are thinking alike.

A Briggs Animal and LO206 engines will bolt on to practically any mini bike or go kart, usually with very little modifying if it had an industrial engine.

The Animal, LO206, World Formula are all based on the Briggs Intek 9.50 engine, which is an over head valve engine (same as the Predator, Honda GX, etc). What will mostly match up to the old flat head for parts is the Raptor. Which was the Briggs flathead 5hp made for kart racing.

Most of the tav2 kits should. But it depends on the mounting holes.

Yes. Most of them I would reckon.

You have to have the side cover that is tapped for the bolts. Some of the early ones are plain Jane.

Ok, here's a new question. Y'all have probably seen my newly acquired 3 HP flattie, but now I'm wondering:
Where can I get performance parts for this engine?
More than anything, where can I get a billet rod for this thing?
I know there are 3 HP billet flywheels out there, but a billet flywheel isn't as importand as a billet con rod.
Also a hotter cam would be nice.

What's the model number of that engine (too lazy to look for it right now)?

Don't have it.
The blower housing is from a vertical 3.5 HP, so the codes are utterly useless.
