OK...
How important is the distance from the crank centerline to the imbalance? In other words: If a crankshaft is heavy at a distance of, say, 2 inches from the centerline and the flywheel is what, maybe 14 or 15 inches in diameter with the eccentric weight 180 degrees off but out near the edge, does this affect how smoothly the assembly spins, even though the entire assembly is "in balance"?
How about the same question if a crankshaft is "light" on one side at the front and "heavy" on the opposite side at the rear?
Is this measurable? No cause for concern?
Anybody care to address "percentage of balance" or is this only an issue with one or two cylinder engines?
Thanks.
