Update: switched carb bodies, no change. They have the parts from the carbs that worked ok. Diaphragm, valves. Anything other than the bare bones.
Also checked: sprayed around inlets and both sides of the carbs all cylinders with easy start to see if it races, it does not. Also tried with a water spray the other way. Tried on the spark plugs too. Float heights seem correct also.
It's 3 and 4 running hard even when the tickover is right down. I get 2.5k on the tickover with the adjuster not even touching, and the balance screw taking 1&2 right up. 3&4 still flying.
The butterflys are completely closed for 3&4 and it still does this. I thought maybe something to do with the choke, but I have changed them with changing the carbs.
I'm at an absolute loss as to what to go after.
