idling issues

Check to see if your throttle bodies are synced

everything you keep describing sounds like a vacuum leak, check hoses again and t-body boots.
if not check resistence of crank sensor.
And the biggie for me when working on any hp engine be it 2 stroke or 4 stroke is do a compression test before you do anything so your not chasing your tail in circles.
after your compression test put in new plugs if you havn't done so already

Check the throttle position sensor also

Suggestion...sounds like flooded cylinder...too much gas will generally bog at idle but will be not noticable at higher rpm.
To see if it is a fuel issue with one carb..let it idle on what feels like 3 cylinders...then remove plugs to see which one is wet. Do this a couple of times
If the same plug is consistently wet, then replace that plug, check that spark lead and get that one carb cleaned.
