Subject: Pietenpol-List: Continental A-65/75 valve guide questionContinental Engine Guru's,My re-print of the Continental engine manual does not give the O.D. of the originalstandard size valve guides. The ones in the engine range from .530 to .550O.D, but I figure they've all been replaced at least a time or two (or three,or four). So, I don't know if I need .010" over, .020" over, or some otherlarger guide I can cut down to size.Anybody know the O.D. of standard size valve guides in an A-65/75?Thanks in advance,Dave MordecaiPanacea, FLwhere NX520SF patiently awaits her crankshaft to return from Rick Roman's.....Continental Engine Guru's, My re-print of the Continental engine manual does not give the O.D.of the original standard size valve guides.
