Bore wise or height . Ya know under the little ball bearing that lays under the pump if I take this out is the jet underneath it removable and possibly blocked ??? Does the ball bearing stick or fail ?

What's the differences in the pumps. They both look identical side by side. It's not a steady trickle it's kinda hit n miss tricklewise

Wel it's a nikki but pretty much same as hitachi dch 340. Think its same layout accelerator pump wise

hi all im new here, ive recently purchased a 1983 910 (maxima) 1.8, im having major carb issues,its the nikki hitachi dch340 carb, when i go to rev the car its borking out, if i rev it manually by the second choke its fine, ive narrowed it down to the accelerator pump as i was barely getting a trickle when i worked the throttle, so ive fitted a new pump but the same thing happening....but if i disconnect the throttle mechanism and push the pump by hand im getting a nice jet of fuel, if i reconnect the throttle im back to a trickle, the pump is returning high enough to give it lift to pump fuel , im really stuck, any ideas please
