How to Buy Your Holley 1920 Carburetor Kit.
Even when you think your carburetor is the original that came with your car, you cannot be 100% sure you are getting the correct carburetor kit unless you match the carburetor number with the kit. You can always take a chance, but then when things are wrong you end up either shipping your kit back, or worst, having to buy another kit because you cannot return the one you have. Many of our competitors do business exactly that way. They let you order by application alone and take your chances. You certainly have that option, but we would rather see you do your homework and get the correct kit the 1st time. It is cheaper in the long run and we aren’t shipping back and forth.The following are the steps that will insure you get what you need for your carburetor.Find the carburetor numberOnce you have the carburetor number, or in the case of the Holley 1920, 1 barrel, the LIST number, enter it in the search box on our web store and click on GO. The correct kit will be listed.

Can’t find the carburetor number? When you can’t identify your carburetor then you are left to do what we have to do when we run into this situation, compare parts. Below you will find all of the carburetor kits that we carry for the Holley 1920. These kits cover all Holley 1920 carburetor with the exception of one carburetor number.

Hint: Start with the carburetor kit that fits your application 1st. There is a good chance you won’t have to look at the remaining kits. In general you can concentrate on two different parts, flange gasket and accelerator pump diaphragm. Below you will find all of our Holley 1920 carburetor kits. Our attempt here is to point out the differences in the kits so that you can make an intelligent selection.
