Title: New needles don't fit!
Post by: bbrian66 on October 09, 2026, 03:09:22 PM

Just opened the new carb refurb kits. The new needles have a step in them exactly half an inch below the lowest of the circlip groves. The needles are all very slightly fatter above the step and won't fit through the throttle valve. Nor will they fit fully into the emulsion tube. (Carbs are 022A)
Have I missed something? Or have I bought a Duff set of refurb kits?

What markings are the original needles stamped with? You may need a magnifying glass to see.

Not sure why you have 022a carbs as those are european carbs iirc. What model is yours?
