I recently replaced the stock Keihin carb on my son's Enticer 250 with a VM 32 Mikuni roundslide. I know have it running. What setting should I put the choke cable at and on the throttle cable how far should I screw it in on top of the carb. Also what is a good baseline for the screw on the side of the carb. I think it is a air screw or idle adjustment screw. Thanks in advance Mike
you adjust the choke cable adjuster till you have around 1/8th-1/4" slack in the cable, meaning you can grab the cable at the adjuster and move it up and down about that much, this ensures theres slack in the cable allowing the plunger to seat on the choke orfice sealing it off, some have a small piston that fits into a hole inside choke opening but same thing.
the screw located on the side of the carb slide body is your idle screw. The screw on the rear bell side of the carb(airbox end) is your air mixture screw, I would start off with it lightly seated and back it out 1.25-1.5 turns out and see how it idles, rev it up and make sure the engine will return to idle right away, a engine that kinda drags it way back to idle speed will be a sign of it being lean, the idle will slowly come back down.

Thanks. What does the one on type of the slide adjusts. What would be a good ball park setting?
