It might also be a good idea to put gauges on your fuel system.
You want to measure metered and unmetered fuel.
You will need this continental adaptor. Continental Tee MS 51523B4
Attached is a chart showing what the numbers should be.

Concur. My avionics shop built a very precise test rig with inline AN pressure transducers to digitally measure the metered and unmetered fuel flows, The rig is housed in a small Pelican case and you can read the displays in the cockpit, making it a one-man job. I do this every annual on my NA G model. Have also done the local twin baron. If you are near central OK, we’d be happy to help you out with yours.
Essentially, you hook up the rig and run the motor at a few select power settings and record pressures. Shut down, adjust as necessary, and run it again. The Continental M-0 manual explains all the steps pretty well. If everything is working normally, a few runs gets the fuel metering and idle speed dead on perfect.
