Can I borrow some carb balancing gauges?

[savvy]

Ref setting all gauges to calibrate the same vacuum, I have the 4 round gauge type and used a 4 into 1 connector from a fish tank air pump and connected all the gauges together on the 4 and fed the single pipe to no' 1 take off and adjusted them to read the same vacuum reading. you can buy them from pet stores, they push together to form a strip.
Hope this explains it.
