Lake, Posa, Star, whatever....... they are pure junk with zero performance gain (losses actually) and only trouble to go along with it
No fuel pump as it's merely a straight shot from the tank to the "injector"
this means they rely on fuel level in the tank which determines "head pressure"
this means that even on a drag bike the head pressure is high at the beginning of a run and lower at the end
so what do you do?
use a remote float bowl which means they then turn into a very crude flat slide carb with no idle circuit and merely a needle for most of your metering
I doubt you can even source various needles (different tapers/lengths) for them so unless you have a shop like mine and can make your own, you'd pretty much be stuck with whatever came with them...... main jet is no big deal since they can be soldered and drilled smaller or simply be drilled larger if need be
far better would be a two or three circuit tillitson type carb....... they actually come much closer to being an injector even without a fuel pump and can be set to "pop off" in the 9-15psi range so they can handle both gas or alky just fine
in conventional carbs....... a dellorto or weber is far better than most carbs
The late Jack Clifford spoke of them (in reference to webers/dellortos) as 'fuel injection without brains'
Reasonably MB and BMW fluent
Love the Kompressor cars....... great when you can find a real deal on a very loved one that still has low miles but various situations have the owner who has been able to afford to maintain it, wanting it gone
