Well there is always going to be a trade off. Stepped up my main carb jet from 185 to a 200. I have some 190's but thought go big then bring down is needed. I'm sure my overall jetting is an air corrector issue but jets are what I have on hand. According to my air fuel ratio # at WOT pulling 11.2-.7 numbers with old and new adjustment. What I was experiencing at around 2500 rpm slightly right before the outer carbs kicked in at cruise I was around 14.6 and a little under powered. Now with a fatter main jet in my primary carb it idle's at 13.1 and I can really push the car off the primary card with and AF# at 12.7.. Cruise for my motor will be around 12.9-13.5. The engine just needs more, I know its running fat but pulls much better with this current jetting set up.
