To sum it up, the 1406 is way lean out of the box. Its the same carb as the manual choke 1405 which is known as performace carb, while the electric choke 1406 is known as an economy carb. Why? the stock 1406 is jetted something crazy like 4 steps lean when compared to the stock jets on the 1405. Even when you rich on the 1406 chart, you are still waaaayyyyy lean on the 1405 chart. The answer was to completely toss the 1406 tuning chart and use the 1405 tuning chart and base settings instead. Take a tuning kit for the 1405 and set the 1406 for the stock setting of the 1405. Then tune from there.
PS: the extremely lean carb will smell just as fuely as an overly rich one. Following the suggestions on that page made my car run/idle 1000% better.
