I was new to duel carbs and got a unisync. Followed the instructions and was amazed that even though I had no clue what I was doing it worked great. lol Chap

Good to know. Will be testing mine out in a few months.

Anyone use an EMPI 43-5712-0?

The instructions say to adjust/sync the carbs to get the same reading by adjusting idle speed and then if required, the idle screws. Seems to me that you would have to iterate between idle speed and idle screws adjustments.
