hi. i did a bit of research in internet and found there are many ways to balance the carbs. among those i noticed that the vacuum gauges and fluid manometers are widely used.
1st question - in a 4 vacuum gauge type, does it measure relative pressure to balance the carbs or does it measure the vacuum in each cylinder individually ( not relatively ) ? the reason i asked this is i can't see any relative connection in between the vacuum gauges as we see in fluid manometers. you can see the pictures below
2nd question - can we use a manometer like in the below picture, which measures two carbs at a time to balance all 4 carbs ? let's say first we balance #4 to #3 (master carb). then cap #4 balance adapter and balance #2 to #3. then cap the #3 adapter and balance #1 to #2.
please give some advice. thank you.
