[QUOTE="Zcat7, post: 473894, member: 14023"] Accelerator diaphragms are good but I guess I could crank them up a touch. WOT seems OK too but it's hard to tell exactly unless I drive another 1776 on the same setup. Pulls much stronger than my old 1664 setup. Starts well and idles OK, although 1 and 3 do suffer from the "robbed vacuum" effect of a shared venturi. I'm running NGK BP6S and changed the plugs and leads after the first carbon fouling episode. Why the carbon fouling on one plug only though? Is the BP6 too cold a plug and combined with the poor air/fuel mixture at idle for 1 and 3, is only showing up on 1 for some reason? Is the timing wrong? [/QUOTE]
