Is anyone running a Y block with three 94 Holley carbs? I just installed a set up on my 292 in my Model A and would like to get a starting point on jet size. What I have now are #42 jets in the two secondary carbs and #49 jets in the primary. I have plugged the power valves in the secondary carbs and have all three of the acc pumps in the #1 hole. This is using progressive linkage. What I have going on right now is that when the secondary carbs open the engine dies unless I cup my hand over either one of the secondary carbs, (choking out that one carb) when I do that is seems to run a lot better. So My thought is that it is too lean (at least on the secondary carbs) What are your thoughts? One more thing, my secondary carbs still have the idle circuits just the mixture screws are lightly seated, it idles fine. In Fact it runs fine with just the primary carb
