What did you do to your truck today! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Adjusted the electric choke and dialed in the mixture screws. Found out they were not adjusted the same as recommended in the Holley manual and adjusted off a bit too.

Truck runs better, but still has a bit of a stumble when idling the truck down a street and trying to step on it. Not always there but it bugs me.

I may bump the timing back up as I have it at 12 and find it cranks way more before it starts, but up at 14-16 it fires right up. Used to be 20 and ran good.
