Holley carburetors are identified by the stamped numbers usually located on the side or the air horn of each carburetor. There are two different numbers that identify a carburetor; a model number, and a list number (sometimes referred to as the part number).
OVERHAUL AND ADJUSTMENTS
It is very important to know that most often the list number will designate the exact model. Included in this chapter is a list of some of the most common Holley carburetor part numbers (see the tables at the end of this Chapter) along with the model numbers.
The model number describes the class, type and general features of the products with that group. For example, the 4160 describes one model of the four-barrel carburetor. The first digit of the number denotes the number of barrels (throttle bores).
The model 2210, 2300 and 2360 all begin with the number two and all are two barrels. The 3150 and 3160 are three - barrel carbs. The last three positions describe differences in the construction of the carburetor, compared to others in the same family.
However, this doesn't hold true in every case. Not all two-barrel models start with the number two - model 5200 is a two-barrel. Carburetors for use with computer control systems usually begin with the number six.
Also, on later model carburetor, some of the numbers listed with the part number are strictly for the date of production.
The list number is assigned to a component as it is put into circulation (this includes fuel pumps, ignition parts and other Holley products). Some list numbers include letter prefixes.
The sales number is for identifying popular replacement parts for a particular carburetor, fuel pump, etc. Sales numbers include a prefix number, a dash number and suffix number are used primarily for ordering and stocking products.
You won't find this number on the carburetor (or other Holley product) - it'll be on the box or the price sheet. Because of this, you really don't need to be concerned with sales numbers.
OVERHAUL TOOLS AND PREPARATION
Regardless of which of the many one, two or four barrel carburetors you are going to overhaul, the initial preparation is the same for all of the following carburetor overhaul Chapters.
Take your time; think about what's involved. Nobody wants to or should have to do any more than is necessary. Are you going to be simply replacing a base gasket to correct a vacuum leak or is the carburetor in desperate need of a complete overhaul?
Shortcuts or quick fixes are nice, but only when the problem is corrected. It's always amazing how there's enough time to fix-it-right the second time around. Organization, cleanliness, good lighting and some advanced planning are all very important parts of getting the overhaul done quickly and correctly the first time.
Many of the parts being dealt with during an overhaul are extremely small and can be easily lost or misplaced, especially if you're using compressed air to clean out passages or dry off parts, so extra care must be taken to keep track of all of the many individual parts you will have separated during your disassembly for a carburetor overhaul.
