Holley Flooding Engine and Spewing Gas

What kit did you use? Most kits come with ALL of the different metering block gaskets. It's EASY to use the incorrect one. That's why I always try my best to get the old gaskets off in one piece and match the new ones up with the old ones. There is one metering block gasket that blocks off a hole or two but the rest line up perfectly. I bet that's what you did. I've done it myself......multiple times.

I took the list number off the carb and used the kit recommended in a part number breakdown sheet I found. According to that sheet, the Renew kit is 37-119.
I tied to be very careful with the gaskets. I just disasembled and checked things over. This one could have been backwards, notice the hole on the left hand edge, one down from the top (sorry for the rotated pic)
