carb hesitation

[Nayls]

Been messing about with the carbs i have & im quite happy with the fuelling,apart from when i change gear & go back on throttle,it hesitates for a second.

any ideas what might be causing this?

Could be either over-fuelling/fuel leaking into the venturi via a dodgy acc' pump jet seal, or the acc' pump jet (read travel) isn't setup correctly (or working at all).

I'l rebuild it then as i did just throw it together with bit's off many carbs using old gaskets just to see if it was any good :scared:

how do i setup the travel on the acc pump?

5mm. I explained how to set it up in a previous thread - I'll see if I can dig it out...

5mm Drill bit against slot beside throttle butterfly, then let throttle butterfly rest against drill bit then adjust the small bolt to ac pump so that the ac pump Is pushed fully in when the drill bit in place.
