I'm putting together a good spare 4412 Holley 2bbl and was wondering which accelerator pump cam to use. I've got a new carb with a relatively small orange one and 30cc pump, but I've used a good old proven carb that has a large red cam with a 50cc pump. I've been playing around on the bench with the cams I've got and adjusting the pump lever and found that there is a big difference in pumping action among the different cams. What's a good place to start guys?
