If anyone knows, I am interested in purchasing this and I want to mount it on a Briggs and Stratton Model 6B S.  The engine does not have any drill holes on the crank shaft side plate for mounting.  I am wondering if this is something I can work with on that engine.  gokart25  is cool with me posting this on this thread so any help in this would be greatly appreciated.  Obviously this is a great deal.
