OK Lets see.



Trying to balance Carbs at idle. The gauge needles are bouncing about like a fan. When I rev it up to 3K the needles level out.



Any ideas?



I am in the process of cooling down to adjust the tappets then try again.

Use an accumulator/restriction to smooth the jerks of the needle.

Only if you have an aquarium with a gang valve. Aquarium air valves work well, or any similar device you may have around the house or garage. Most of the big box stores which sell pet supplies have them, I saw a set at Wally World for $2.99.

Never tried it, but you could probably jam some cotton swab into the tube
