The SK carbs are very similar to Weber DCOEs. Mounting flanges are the same,
The brass bits, like emulsion tubes and jets are the same as the Weber parts,
so getting those is fairly easy. The SKs have a couple of vacuum ports for
distributor advance connections, something that earlier Webers do not have.
So one could claim the SK carbs are more streetable.
Tuning the jetting to your application one would use the same guidelines as
Webers. For example, if you have no idea where to start on the jetting, start
with a main jet that is 4 times the size of the choke and see where that gets
you. That is, if your carbs have 30mm chokes, use 120 main jets.
The chokes are unique to SKs, so they may be a bit harder to find. Hmmm, I
think it might have been Pierce Manifolds that bought up all of TWM's stock
of SK stuff when TWM dropped carb sales and went strictly fuel injection.
I was going to say I have an SK carb on Racket, my Mark 1 street Spit, but that
carb is actually on Pugs' Herald.
