CounterweightedmodelA crankshaft

Posted by Cass Stewart on August 15, 1997 at 16:01:24

Has anyone had any experience with adding counterweights to a model A crankshaft?If so, is it difficult to do and does it smoothe out the engine vibrations.Also, is a corresponding amount of weight removed from the flywheel?.
Any comments will be appreciated
Thanks;
