Does anyone have first hand knowledge of "de-tuning" the crankshaft counterweights by applying throttle to fast?
I assume this would manifest itself by a change in vibration?
How are these weights secured and "tuned"?
Is this peculiar to specific engines?
Wow!
I have an AEIO-390 with a countweighted crank.
There is no manual, specific to the 390. I was told to use the stuff for the IO-360 (200 hp) engine.
The Operator's Manual, that I have, warns against applying the throttle too fast because there is a danger of "de-tuning" the crankshaft counterweights.
