Guy,
I run HS6s on my TR4. They came off a 67 4A. I have zero trouble with
them. Car idles fine and throttle response is similar to my 3, which has
H6s and my 6 which has the Hitachi HS6 carbs. I think you may have a
vacuum leak somewhere, manifold most likely or maybe a problem with the
float valve? What fuel pump do you use? I have the Facet model on all 3
running about 2PSI at the regulator.
But even with the mixture nut all the way up, there will still be fuel
to the throttle body that is if you have the needle installed on the
piston correctly.
