 They are not difficult to work on, but the butterfly spindle bores wear out. If the throttle axle has radial slop, find yourself another set of carbs, the air leaks will make you chase your own tail until dizzy.

The concept is actually quite brilliant, needle profile maps mass air flow to air/fuel ratio, similar to early fuel injection systems. Later computerized injection systems added another dimension - engine speed - to the air/fuel ratio control. Not strictly necessary for performance but vital for emissions and economy.

That being said, I am not a fan of the 907 Stromberg inlet manifold, being 540/180 degrees rather than 360/360 on the cylinders it is feeding.
