If you have an adjustable timing light, you might measure ignition timing at idle and with the engine at about 2000 RPM. With the load-a-matic system functioning properly, you should see the ignition timing advanced about 20 degrees at 2000 RPM. Good luck.

Everything is good. I tested the vacuum at the carb and at the distributor. It was just very badly out of timing. Owner picked it up and said he can go 60 mph now! lol.
