<p>Guy,</p>
<p>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.</p>
<p>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.<br>
