Thanks Neil,
So a needle with 0.090 is related to the main jet size of .090?
If so then I didn’t know this relation ship between needle and jet size existed!
and if I have an mis match then may explain the hesitation in accelerating unless the choke is out a bit to make it richer.
I will be checking…

Gary
My next question is: for an A7 running an HS2 what main jet size is used?
Gary
