The air cleaner that came with my engine has a 5 1/8 hole where it fits onto the carb. My original carb was and Edelbrock, now I have a QUick Fuel. Both have 5 1/8 hole, and mine had a 1" spacer so that this air cleaner would not rest on top of the distributor.
The difference is that a the Quick Fuel choke linkage above the area where the air cleaner fits hits the 1" spacer and is actually wider than the 5 1/8 area fitted for an air cleaner. DO I need a specific Quick fuel spacer or air cleaner.?
