Engine Dieseling - Options?

I never try to set the air screws the "same". That's just not the right way. You adjust with the vacuum gauge. Get each one to the highest reading on the vacuum gauge, in gear if an auto and then one half turn leaner. "Wherever" they end up is where they are supposed to be after that. That's how it's always worked best for me.
Well yeah, I didn't mean to say you just make them the same for the sake of making them the same but they should end up close on a 4-corner carb ....I shoulda been more clear. But,1/4 turn out on the secondary and 1/2 on the front tells me something's not right.
