Hey All,

I was wondering exactly how much air should be going through the Synchrometer. I have the adapter and the synch but no instructions. And the how to tune weber carbs book doesnt really go into specifics about using this thing.

Thanks

Assuming that you are using a unisyc type flow meter.

Make sure the float tube is vertical when tool is mounted on the carb, then turn the adjustable piece in the center of the tool in just enough to cause the indicator to rise in the float tube to match one of the marks. You should use the least amount of restriction to achieve this. This will give you a benchmark to match the other carbs to. You do not readjust the tool at the next carb, you adjust the carb to match the flow rate of each other.

It will be clear how the tool works once you use it.
