...interesting dilemma here..... swapped out a pair
of ZS carbs for HS4's I've plenty of experience with tuning
SU carbs but this one is a bit of a 'stumper'
My best setup.... has A/F at around 12.3 at idle.... but up and running,
cruising, and 4th gear 20-50mph ace te4sting all looks (and feels)
great!
I simply don't understand the idle being so rich. If I lean out the idle...
it wants to die. Yes... testing included with, and without air filters.
8 sets of needles, and not much difference.
ideas... suggestions.... maybe I've simply overloaded myself here
while doing all these carb comparisons. HELP!
