Weber 48IDA carbs are fun to tune and sync.
Kind of amazing if that is the first start that the carb linkage and carbs are synced and tuned that well.
Must have a light flywheel and no clutch for that kind of response.

An engine stand puts no load on the engine so you can't seat the rings on it.
It's really not good for an engine to freewheel on the engine stand, dyno is better.

Our race car has good response but it has a 7 inch diameter dual disc clutch, less rotating mass.
