Carburetor Calibration Tuning Kit Jets Rods Springs Replacement for EDELBROCK 1407 1410 1412 1413 04-02-10 06:06 PM - Post# 1891808 My Eddy 1406 is running rich. Buy the Calibration kit for the 1405 and put in the baseline jets and rods to start. What you might discover, after comparing the OEM fuel calibrations (jet and rod sizes) to what's in the carb I was wondering if anyone could recommend a baseline jetting for my combo, IIRC it currently has the 1427 main jet and 1455 rod on the primary side and the same 1427 jet on My 383 -66 converted from 2bbl to 1406 end up with a quite odd and lean jet/rod combination to run best but it's different from engine to engine what you end up with. Still rich but I think Edelbrock 1406 Isky RV cam Stock air cleaner Any help is appreciated, I'm new to carbs and really need some guidance. Verified Purchase. OUT OF STOCK. The rods have two settings: rod-up/low-vac and rod-down/high-vac. In Stock. com, for good measure. The problem is the stock 1406 carb is jetted so lean that you are starting from a whacked benchmark, so even the chart is misleading.

I tried the stiffest springs in the 1406 edelbrock kit with not much change. I took the top off to check the float level and drop. The idle jets on the 1406 are small about 36 thou orifice size.
