Bill,

Opening the idle needle a LOT will make the transition far too rich.
I have this problem. It idles too rich, loads up and dies. Also, the throttle barrel hits the spray bar housing and prevents full closure of the throttle. I have tried everything except properly
setting the midrange by turning the spraybar so the fuel metering slot points to the rear to lean out the midrange.

With the fuel metering slot in the spraybar pointing down, one can get a good idle and a good top end, but a massively rich midrange. Please explain the proper procedure for turning the
spraybar to set the midrange.

Thanks,
