Removed the vent tube (Was sticking out from the gray JB welded spot seen in the pic between the choke shaft and the idle solenoid) with the line that went to the charcoal canister and plugged it with JB weld.
Replaced the primary jet with the secondary jet # 180.
Leave the secondary jet open.
Spread power valve spring apart @ carb body end by 3mm. for power valve to open earlier.
Drill out power valve discharge nozzle to .039 (Drill # 61)
By the way, these are pics of the spare carb that i stripped to figure out how the carb circuits work- the crap at the bottom of the float bowl is what i found in every one of these carbs ,a reason why these things usually need a good cleaning to run right. These are all the mods done to the carb besides from stripping it to bare essentials -removing all vacuum actuators and vacuum lines except for the vacuum advance that i kept on only to keep highway temps down (Advance is locked in @ 28 degrees)
These are only preliminary jets and settings .Maybe someone else will try this and get better results with different combinations of timing, jetting and orifice sizes.
