Hi everyone, I'm wanting to install a predator style carb on my Briggs flatty. Has anyone ever tried this. I'm going to make an adapter to bolt it on. What material would be better suited to use, aluminum, delrin, or plain steel? Also how does the length of the intake manifold affect how the engine performs? Like would a shorter intake have less bottom end and more top end or vice versa? Anyone that's done this care to point me in the right direction? Thanks.
