45DCOE 152W (5 progression holes)
Genuine Spanish Weber carburettor
Over the years it has become apparent that the fitment of 45 DCOE carburettors to certain newer types of engine such as Ford Zetec and Duratec will result in a flat spot just off idle that no amount of calibration will eradicate.
Webcon have studied this characteristic in detail and have developed a very specific procedure to modify 3 or 4 progression hole models to 5 progression holes. This allows precisely the correct extra amount of mixture in the progression phase to overcome this flat spot and results in a smoother more progressive transition from idle to main with no flat spots.
