Engine stalling

Question : MY car is having a problem in the morning or when the engine is cold.

The engine tends to stall for the first three minutes before the temperature rises to normal.

With twin carburetors, no mechanics have managed to fix this problem.

I was told that I need to change the two carburetors but the mechanics did not recommend this because they are unable to do the tuning.

The car condition is still tip-top and I feel that it would be a waste if I can't repair this problem.

Answer : I am not familiar with the set-up of this engine but I would assume that the twin carburetors are fitted with automatic chokes.

If this is the case, one possibility is that the power lead tot he chokes has either been disconnected or fused, such that the chokes are not being activated when the engine is started as the bi-metallic element inside closes the choke to enable easy starting and then opens as the engine warms up.

The cause of the engine stalling is because the air-fuel mixture is too weak when the engine is cold.
