 Ok! Working on all the carb specs. In the meantime, here are what the idle screws turns were:

1 5 3/4
2 4 1/2
3 4
4 3 1/4

Adjusted 3 and 4, rebalanced carbs (STE synchrometer) and coughing went away. Yay!

But plot thickens. Have a carbtune hooked up and could not get #4 to balance with the others. #4 doesn't appear to be firing. Cover intake and no change. Have a good visible spark and checked also with timing gun. Switched plugs. Switched idle and main jets. No change with spraying starter fluid. Grommets on top are 2mm spacing. Thacks at bottom 1mm between coils. Soft mounts all even. Air bleed screws closed. Verified wired for 1,3,4,2 firing order. Disconnected carbtune amd put screw back. Did have some grey exhaust smoke but it went away. Did not smell gas in exhaust. #3 is firing so can't be floats. So also befuddled as to why coughing quit after changing mixture and rebalancing carbs and #4 was not firing...
