hitachi 4 bore help

bowjangles · 06-05-2014, 04:38 AM

I have a '74-75 Hitachi 4 bbl carb on my old 13 B. Recently, I noticed that the linkage for the secondary throttle is not connected in any way to the primary throttle via linkage.
Maybe there is a rod , or something missing As a result of this, when I kick the pedal down the secondary jets never contribute/squirt fuel... so performance is very wimpy.
What I need to see is a diagram , or photo of the forward side of this carby so that I can connect it properly. I have searched the internet extensively and have found nothing to help. Thank you

Pretty sure on mine, the secondaries are controlled by a vacuum solenoid. I'll double check and let you know.
