Looks like you have improved manifolding as well which will help breathing. My immediate thoughts are that you have it a little too rich. My Nippy runs very well on 80 Main and 50 Comp, it is an unmodified Speedy type engine, factory head, cam, manifolds etc. I will probably have a larger choke tube than you though? I have in my notes from other cars two similar carbs C855A and C1228 both engines were well tuned with modified cams etc on those 85/55 and 95/65
