Well I got the carbs back from Lockwood. They did a two hundred hour inspection on them and sent them back despite my specific instructions to run them on their test engine first.... Not that mattered, it runs just the same as before. Rough between idle and 3000 rpm,smooths out above. I thought the A box was running rougher than the B box so I swapped the plugs. The roughness seemed to move to the B box. Again it is only a small difference between the two ing. circuits and the rpm drop is the same. I've checked all the wiring best I know how and cannot find any breaks. New plugs and fuel.
I'm really getting tired of this motor.
