Engine timing 2.0L, Calling all engine tuners Options

[R Dub]

I need to know what the correct timing for a 2.0L (built to 2056) with and electronic ignition, no vacuum advance running dual carbs.

I set the timing to 27 degrees BTDC per the manual but it doesn't run right, it seems much happier with some timing taken out. Any help is greatly appreciated. Thanks in advance.

I know you said the carbs were rebuilt. But have you balanced them on the engine to make sure they are drawing the same? You can do it by ear, but using a snail gauge makes it a lot easier. Tuning carbs by ear is an art. The popping you are reporting makes me think the carbs need work.

Is the car fully warmed up when you are checking timing? Cold carbs draw very differently then fully warm ones, and if you tune the car for a cold engine its going to misbehave badly when the engine is warm. Tuning for a warm engine can mean you need to play with the throttle when the engine is cold and give it a moment to warm up before it runs well and you are off and driving.

At 1500 RPM the car is only barely into its advance curve, unless the curve in the dizzy is really wrong (like a generator curve or something like that.)
