This will enrich the mixture when going up hill or accelerating hard, and lean it under heavy braking or coasting downhill. When it's mounted backwards, the fuel level in the float bowl is effectively raised under hard braking or pointing downhill, and it will flood the engine enough to make it sputter pretty hard or stall.
I might have to do that myself, because I work on top of a mountain and extreme uphill/downhill is going to be an everyday thing. lol

Did you have to lengthen the brake booster line when you flipped the Weber around? That and the throttle linkage might get a little weird...
