I’ve got a Holley 4 barrel with list number 1850-3. From what I can find this means it’s a 600 cfm with model number 4160; however, mine has 3130 as the model number. So my question is does this model number indicate a different carburetor when trying to buy rebuild kits or should I just get a rebuild kit for a 4160?
