Hell yeah!What I mean by a pumper carb is a carb with a diaphram that gets a pulse from the engine sump. The pulse hits the diaphram and the diaphram forces a squirt of fuel to the intake charge, after the pulse a needle shuts off the plumbing until the next pulse - sort of like fuel injection but without electronics. No float bowl. These type carbs were popular on McCulloch go cart engines and I saw a magazine article where one was adapted to a BSA 441. That BSA used a pulse from the exhaust pipe with a line tapped in near the riders foot. They measured a HP improvement but that's as far as it went.
Come to think of it - this is one of the few carbs that would fit in the Norton twins restricted space and it might be a great alternative as a twin carb setup.
I used to cut wood for a living and I have one of these racing motors in my chain saw and it absolutely kicks ass as shown below.
