1405 lean at WOT
One more thing. Cruise at 35 mph is very different than cruise at 65 mph.
The difference is mostly the load at 65 is higher, this requires more throttle opening and is the place to judge if the primary main circuit is too lean. When its too lean, you'll know it! Just back off the throttle and drive slower until you an get to a safe place to change the rod/jet combo.
Assuming the off-idle was close, the transition will then be pretty close.
Next thing to fine tune if you want is the enrichment point. This one is not easy. Use a video or a friend to help. Power should increase with increasing throttle (and corresponding drop in vacuum). If there is a dead of flat spot, or if the power suddenly increases with the step up raising the rods, then the step up point needs to be adjusted. For increasing power, AFR should be going leaner with increased throttle opening - until it needs to go richer. That's what the step up rods do.
