I understand that there are two ways to set up the Holley 2x4 linkage. I would like to know what experiences members have had if they tried both ways or have knowledge of the differances.
1. Linkage set up so that both carbs open at the same time
2. Linkage set up so that one carb opens and the second carb progresses in as the original linkage was made to function I believe.
