On my LNC2-360 (BIB plus high comp pistons) there is an add-on "balancer" b= olted to the face of the starter ring gear.

The "balancer" is about 2 inches in debth and almost the diameter of the ri= ng gear=3B it is all self contained and you would have to take the prop off= to get it off and take it apart if one was at least currious what was insi= de of it. =20 It's difficult to know if a 4 cyclynder Lycoming is as smooth as it can be= =2C because it's not a real smooth engine under the best of conditions. =20 I inquired to a local experienced prop balance person in Redmond and they c= oncluded that because of the dynamic balancer on the ring gear=2C he would = not attempt to balance the engine with his expensive balance work=2C as he = thought the attached dynamic balancer would change the internal weight at w= ill. =20 Does anyone have any experience with these dynamic balancers attached to th= e ring gear??? =20 Cheers =20 Jack Addison N360JS near Redmond=2C OR = --_92a97cdd-3a69-4dff-8497-b7d3d1f9b61e_ Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Question?

Does anyone have any experience with these dynamic balancers attached to th= e ring gear???
