Confirmation of adjustments on H carb

Thanks Rusty,

correct. It was running rich, but I think the bad points may have

Factory initial setting is 1 1/2 turns out on the idle mix screw, and 3 turns out on the load screw. The load screw does not need to be adjusted while setting the idle, in fact, there really is no need to even adjust that screw after the initial 3 turns out.
 
I will check the load screw.

It does not hesitate, nor load up when I open the throttle. It is
running a lot stronger with the new points. I think it needed the
richer mixture with the weaker spark.
