<br>I was wondering if anyone had any experience using the calibration kits for the Edelbrock performer carbs. I have a #1406 carb bolted to a performer intake sitting on top of my 302. My engine is basically stock except for a set of headers and a Mallory Unilite ignition. <br><br>Overall she runs very good with plenty of power. I advanced the initial timing to 12 degrees and now it idles better and has better acceleration. However there is a little bit of a stumble if I stomp on the skinny pedal. Plus it still smells like she's running rich even though I've adjusted the mixture screws as lean as practical. <br><br>I'm thinking that a calibration kit might help to tune the carb to my application. I figure somebody around here has used one of these kits before and can tell me the best combination of rods, jets, and springs to use. Otherwise it'll just be a process of trial and error I guess.<br><br>The kit for the 1406 carb contains the following:<br><br>Metering Rods (Pair)<br>.070 x .042 #1450 <br>.073 x .042 #1455<br>.073 x .047 #1456<br><br>Metering Jets (Pair)<br>.095 #1426 <br>.098 #1427 <br>.101 #1429 <br><br>Step-Up Springs (Pair)<br>3-inch Hg Blue<br>4-inch Hg Yellow<br>5-inch Hg Orange<br>7-inch Hg Pink<br>8-inch Hg Silver<br><br>An yes, I know that some of you guys will tell me to convert to fuel injection instead. That's my long-term plan, but until I have the $$ and time this will have to do. Any help would be appreciated.
