Ed and Bill,
Just some ponderings as I progress along my way
of understanding different carb developments.
I notice with a slide carb ( round on round
opening) you get more of a straight line function of air to fuel ratio
as it progressively opens.
With a flat slide on round opening you get
'diminishing returns' ( my term) as you get past half way.
I notice that some carbs have eggs shaped
openings, I guess that's to even out the percentage of fuel/air mix to
percentage of opening and to compensate for the enrichening at higher RPM i.e.
more air to fuel at higher rpm at the fatter end (top).
I was wondering what was wrong with a square carb
- not completely square mind you, but with some roundness to corners say
1/2 diameter.
Wouldn't this provide for a more linier opening
to fuel/ air ratio mix OR does this pose other problems such as air flow and
drag/ turbulence?
