Title Page:
When it comes time to rebuild your Holley carb, tools and parts selection is important. This stand allows pivoting and rotating of the carb a full 360-degrees.

Top:
One of the first steps in disassembly is to remove the float bowl. Four screws hold the float bowl to the carb body. Once the screws have been removed, a light tap with a plastic mallet usually frees the float bowl from the metering plate.
Middle Left:
Install the main jets to the metering block using a dedicated jet driver instead of a conventional screwdriver. A Holley jet tool safely captures the jet and eliminates accidental slippage or burring of the jet’s drive slot.
Middle Right:
On the metering block, you find the idle-mixture screw. Notice the cork-rubber gasket in the hole recess. Use a small pick to remove this gasket. Always plan to replace this gasket because it can be easily damaged.
Bottom:
When assembling the carb, slide the fuel transfer tube on the float bowl. Slide the fuel bowl into position while allowing the fuel tube to slide into its rubber seal. When fully installed, the bulge at each end of the tube should be seated against its rubber seal.
