Looking for setup info, documentation, or pics on the mods that were made to the Mikuni 42mm carbs used with the 53mm Aerocharger Turbo.
It had a 4.2 needle and seat installed. Have a 2.3 ordered.

Thanks in advance.

Vacuum line purpose? Accelerator pump disabled via adjustment screws. Obviously it has struck the cam many times before though.


Piece of vacuum hose around accelerator pump rod. Seems to be attached to the carb housing. Possibly started out as a vacuum line cap.?


Diaphragm / seal over accelerator pump plunger. It has a hole / tear in the middle from accelerator rod strikes.
