I got these needles from a set of MC18 carbs by a local shop.
Can you maybe send me codes on the right needles that should be
used. I also understand that it is hard to find these needles.

Just a question, does the original MC21 carbs have adjustable needles?
Some people say they do and others don't. I have got the
1992 MC21 SE.

Thanx for the reply
