This month’s performance tech took us out to the Carb Shop in Ontario, California. The crew there helped us with a Holley rebuild about a year ago and while we were there, they told us about a number of other carbs that they are able to service. When we picked up our matching-numbers classic, we knew that we wanted everything refurbished, and that included our carb, so a return trip was needed as we wanted to maintain the value of our latest project.

When I pulled off the carburetor, I assumed that it was a Quadrajet-style carb, but in reality it was actually a four-barrel carb, which was the foundation to a current Edelbrock carb. We found that some of the parts were the same, as the design was hardly changed over the years.

In this tech, we took the four-barrel and resurrected it from the graveyard as OJ tore it down and completely fixed it, allowing us to get a few more years of service. Now follow along, as the carburetor experts crack it open and remanufacture this classic carburetor.

<strong>1</strong>. This old carb has seen better days.<strong>2</strong>. OJ tore down the carburetor, making sure not to lose any of the small parts.<strong>3</strong>. After finally cracking the carb open, we were able to observe how much gunk had built up over nearly 50 years of use. While tearing down the carb, OJ noticed that it had never been molested and still had all of the factory internal parts.<strong>4</strong>. This carb had bad residue from its years of service.<strong>5</strong>. Once the carb was in pieces, it was given a hot soap bath to remove most of the grime that engulfed it.<strong>6</strong>. All of these parts are the internal pieces and working mechanisms of the carb.<strong>7</strong>. Even though the carb and some of the parts were soaked and cleaned for a long time, they sometimes need a super cleaning with fine glass beading ding.<strong>8</strong>. OJ made sure to clean all of the cracks and areas of the carburetor.<strong>9</strong>. The carb was all clean and OJ started the reassembly of the carburetor.<strong>10</strong>. The jets were screwed back in.<strong>11</strong>. Before anything was bolted onto the carb, it had to be inspected to make sure that nothing was clogged.<strong>12</strong>. Both floats were measured using a caliper. This ensured that both side of the bowls received the same amount of fuel.<strong>13</strong>. The old fuel plunger was made from leather and worked good for its era, but we are going to update our carb with a newer plunger, designed for our fuels of today.<strong>14</strong>. The carb was ready to be sealed.<strong>15</strong>. Some of the external mechanisms were attached so we could wrap up the rebuild.<strong>16</strong>. Once the carb was rebuilt, it was put on the dyno so it could be checked before delivery. This process is done with every carb that the Carb Shop works on.<strong>17</strong>. The pull on the dyno made 540 hp with this carb, not too bad for a 49-year-old carburetor that was almost thrown in the trash.<strong>18</strong>. This carb was ready to be bolted back onto the engine that it came from.
