And something else, check the 12 V power supply to the CDI. As you see in the wiring diagram, the orange/white wire going to the CDI should have +12V with the ignition ON.

Sorry , Can't help on the tach . I see I mistyped in last message It should have been 2 turns , not 3 , but turn it about 1/4 turn at a time. Turn it in or out a bit when you find the spot it starts ok and doesn't die when you open the throttle to fine tune that sweet spot . It should run after a couple of minutes warm up and not stumble when you "blip" the throttle .. If it does , it can be because it is too lean at idle ( air screw out too far ) or a problem with an accelerator circuit.. It's hard to cover bases with suggestions from afar, especially when not familiar with the specific carb(s) on various bikes. All I can do is point in directions to look for problems.
