Try inserting a skinny wire in the idle air bleeds in gear to see if that helps on the idle AFR If it does that means it wants smaller idle air bleeds which enrichen the mixture from idle to WOT On the fat when cruising you might be able to lean down the transition fuel feed channel, take the carb. apart and look at the slot in the middle of the throttle body that the throttle plates straddle, I drill and tap them for a allen head #6 brass set screw and then drill the set screw to make the channel smaller, make sure and figure out what size the stock hole is before drilling and tapping I bought two numbered drill bit sets, 1-60 and 61 to 70 with a pin vise to work on carb. circuit slike those You can make the babys (carbs.) purr like a satified kitty As already said work on one circuit at a time, remember the idle circuit, the transition circuits, the primary and secandary as well as the power enrichment circuots all work at WOT The idle and high speed bleeds should be used for the final fine tuning BTW, check your ignition timing from idle in nuetral to idleing in gear to see if that rascal is dropping the lead out of the mechanical advance at the lower RPMs Keep at it, you know your having fun and learning, correct
