It seems I remember you can test your engine to see if it has sufficient carb size with a better quality vacuum gage. The test is run on the road with wide open throttle. At wide open throttle in the upper rev range an undercarbuerated engine will pull a small positive vacuum because it can't fully satisfy the engine demand. If the engine has adequate or too much carburetion it will pull petty much 0 vacuum signal at full throttle. At least that is what I remember.

Anyone hear of this and try it before?
