New needles don't fit!

(1/4) > >>

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?

Oddjob:
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?

Hi Oddjob
I'll check the needles in the morning. The bike came completely dismantled with lots of parts missing. It's an F2. These carbs came with it. I was going to change them, but they're in really good condition so decided cheapest was to clean them and use them.

Oddjob:
A UK F2 should be wearing 069a carbs. However I’ve known a few now where the carbs have been exchanged with a European restorer whose name escapes me right now. He has sent 022a carbs instead of 069a carbs not thinking there may be a difference. I think the 022a were fitted to the 550k models Europe got.

We’ll know more when you find the number stamping.

Carbs are all marked 022A. The one needle I've removed is stamped 272304, which looks to be the correct needle for this carb.
I was hoping to use these carbs as they are in really good condition,  but are you saying i should source a correct set of 069A?
