I looked up the
Twin Max Carb Synch Tool on Google and did a bit of research (Having never used it). I'm impressed. It measures/compares two vacuum sources and gives you a meter reading of the difference. No difference = "0" reading. With only one sensor in the loop, there is less chance of error.
I don't have any experience with the tool but can't help but think that it would be better than mercury, tubes or vacuum gauges.
BTW, are you able to snub or reduce meter fluctuations?
