K+B with Irvine Carb
I bought a box of old engines at a garage sale. One of the engines is a K+B 40 with a Perry pump and an Irvine carb. Back when the K+B 40 was common I had 4 or 5 of them. None of mine were pumpers and all had a perry carb. Anyone know if this pump and carb set up were factory?

As far as I remember it, the K&B pumper engines all has Perry carbs on them. The Perry carbs were special for pumped engines with a more lean midrange and a larger inside bore or venturi as the engine doesn't need to draw fuel with a pump on it. They still sells the special Perry pumper carbs too.

RE: K+B with Irvine Carb
Sometime around 1979 to 1980 I bought a brand new K&B .40 that came equipped with a grey plastic Irvine carb. No pump. It worked perfectly. Shortly after that, K&B started shipping engines with their own metal carb, but it wasn't the Sportster style metal carb. It looked as though it were carved from a big block of aluminum. They worked just fine too.

My K&B Pumper came with a grey Perry pump carb. I bought some used K&B .40's that had a black Irvine carb, but they were unpumped versions. Being as how they were used there is no telling how they were sent from the factory. I always thought the pumped version made exceptional power for its weight.
