Hello Guys, Question on the 4k intake manifold. I'm fitting a weber 32/36 and have an adaptor plate. As i don't know as much about carby stuff i thought id put the question up here. My adaptor plate is an oval shape however the ports (i guess you can call them that) on the manifold where the original carby bolts up is two circles, one smaller than the other. My question is, if i remove the centre of this to make it the same shape as the adaptor plate will this help or hinder air fuel flow? Photos show what i mean. The part shaded in red is what i would be removing. Before After
