Carburetor Adapter for Briggs & Stratton Engine

[Flinx]

I have a couple of old B&S engines model 60102, 81102, and 90102. Does anyone make an adapter to use float type carburetors instead of the stock carb that is mounted to the gas tank?


the attach point is at an angle.

I have done some googleing and found something for predator engines but nothing for B&S.

Aha! Welcome to the Briggs flathead addiction my friend!
I've got a Model 8 3 HP as well! From those codes, you have a 2 HP, a 3 HP, and a 3.5 HP.
Not a ton of mods out there for the smaller ones, most of them are for 5 HPs.
I have some OEM float carb suggestions for you: Flo-Jet updraft carburetors.
Below is an older picture of my 5 HP with a Flo-Jet updraft, to give you and idea of what it'll look like. The intake manifold allows the carb to be bolted level.
Here's a few on Ebay for your size engines:
https://www.ebay.com/itm/briggs-str...745367?hash=item4b62a851d7:g:SbMAAOSwdJ9aGzS1 About $40.
https://www.ebay.com/itm/briggs-str...470543&hash=item2f2947a924:g:P9gAAMXQOT5Q~lUD Again, about $40.
You'd still need a manifold.
Can't remember the part number off the top of my head, I'll try to find it.
A member on here, KartFab, built a Bronda engine, putting a Predator 212 carburetor on a Briggs flathead with a custom intake.
If you want a float carb and an upgrade at the same time, look into a Mikuni or Keihin slide carb.
But all of these options will probably be more expensive and complicated than fixing up the stock tank mount carbs.

Simple as making your own with 1" or so steel tubing and some flat stock (or large washers) to make the flanges on either end.

However, the stock carburetors are nothing to laugh at and can be tuned somewhat, especially if they have adjustable, and not fixed jets.
