Last time we chose a manifold based on flow volumes, and a carbie based on personal choice, but which combination is best on this engine? With the engine finished, it is time to look at a variety of carburettors, inlet manifolds and exhaust extractors, to fnd the most suitable combination. There are a lot of fgures, but they are necessary, so bear with me.
One of the common problems where sidedraft carbs are involved is the choice of carb size in the first place and choke size in the second. The trick with carb sizing and choke selection is basically one of choosing a size which provides the engine with the airflow it needs without going over the top.
