Tom, I am certainly trying my best....formula428...you have to define "cruise" to know what circuit to try and enrichen. If you are 2200 and up, then yes you are probably on the main circuit. If you are talking super light throttle, then it is probably in the TSlot/IFR circuit.
Low rpm loads w/ OD trans are more tricky to get all tuned in. It is feeding off the TS down there. Sometimes I drive around 16-1800 just barely touching the throttle, but definitely loading the engine.
Are you using AF meter of some sort?
