You should set up the carbs to have equal "suck". A vacuum method is usually the most accurate. It's rare that the jet settings on both cabs are exactly the same and maybe there will be a couple flats between them to get a smooth idle and best general running. As you've had your carbs rebuilt you shouldn't have the idle setting problems caused by worn spindle bushings so you can try a flat or half a flat even up/down each side to get the best result. Use the instructions in the Haynes regarding the lift pin. Not everyone's cup of tea wheb tuning but it does give you a bit of an idea. I 1/2 turns down is 12 flats. You might end up with 10 1/2 and 11 3/4 or something like that. Not usually above 12. Someone who has tuned a lot of pairs may say that the front carb tends to run weaker than the back, or vice versa, as far as the number of flats go. Comments welcome on that.
Good luck George. Being in a hot clime, if you never need choke to start, you can probably come down at least 1 flat.
