Due to a few conflicting local opinions, I wanted to check in with the Cub collective here:
Are Lycoming four cylinder motors externally counter-balanced via the flywheel? There are holes drilled in an offset pattern in the flywheels of 235/290/320s/etc, and these holes are large enough to (possibly) not be balancing the flywheel itself.
Without an alternator nor starter, is there a need to retain the flywheel on O235/290/320s (outside the need for the prop spacing)? Or, is the proper flywheel an external counterbalance which must be retained?
Specific to my application: O235, no starter or front-mount alternator, Catto prop; large spinning disk of a flywheel up there doing nothing but spacing out the prop from the nosebowl.
