I'm running a 26mm mk2 amal open mouth and have been for about 10,000 miles. It's gradually running a bit spluttery/riche lower down the revs and i've gradually lowered the 2B1 needle to compensate. It's now on the top ring so can't lower any more but just wondered if it's possible the needle could be worn? Could I just replace the needle and raise it a bit again or is the next stage changing the needle to the next one down? If so, what would be the needle required to have it on the lowest ring (highest positon for needle) and be approximately the same as a 2B1 on top position (if this makes sense)
