Continuing ignition timing debate from the 416 thread.

Not really.
An engine should go from 600 to 1400 rpm without enrichment.
Pump shot is needed only when the throttle position changes rapidly. It shows as a blip on WBO2.
Enrichment is needed for full load.

Thanks for the correction. I'm not an expert in tuning. Just an engineer with a solid grasp of fundamentals.
