Hi All,

Are there any good engine guys out there who can help me diagnose an rough running engine???

Here is a video of the vacuum gauge with the engine running at various engine speeds:https://youtu.be/1YYV77zbxog

The engine is a 1949 Packard Straight Eight and it was just rebuilt. I just adjusted the valves hot and replaced the spark plugs. All cylinders were compression tested and all are within 107 and 118 PSI during a hot compression test (spark plugs out and 5 compression strokes).

Can anyone PLEASE offer some suggestions/advice???

THANKS IN ADVANCE!!!

Bill
