Don't sweat the number of turns on the idle speed with Spanish 38mm models of the DGV class . It's not uncommon for casting differences to change the distance a bit . It is somewhat important to balance the number of turns out on the idle jets - that should be corrected . Once you equalize the idle mixture screws and set the correct idle speed it should run very smoothly , unless you have a weak cylinder or two . Small things show up running these carbs , they are not as forgiving as the stock units on any engine .
I'm curious - do you know what number is on the emulsion tubes below the air corrector jets ? I would assume it is an F50 , but one never knows ...
Remember , idle jet size is determined by driveability - if it wants to stumble a bit or cough just off idle , idle jet size should be increased . One key to know the jet size is correct is having a very sensitive throttle - input should produce very rapid changes in the engine , it will drive like fuel injection when it's right .
