differences between IDA and DCOE
just curious...

outside of this is there any other differences? flow characteristics or such? what about manifold options.

Tennis, anyone
the dcoe is side draft, on most piston engines the manifold is short and the idea of side draft is intake on one side of the head and the exhuast on the other side.
cross-flow, the design is about the best for N/A. ida, is down draft and the manifold is more less a single plane. a ida has a progressive linkage. primary and secondary butterflies and can be set up with good results. dcoe uses no progressive type linkage, both (v's) butterflies open the same amount at the same time and work the best when syn'ed together. single plane manifolds have an open area directly under the carb. pluenum and off the that are each 'runner'
to however many ports the intake/engine have. 4 , 6, rotory.

DCOE's are sidedraft street carbs. IDA's are downdraft race carbs, and they don't have things like chokes. (IDF's appear to just be downdraft versions of the DCOE, but I haven't played with one in person yet!)
