I have the new style timing gear shaft seal that does not leak and an old style roller timer. Is it necessary to install the thin metal disc behind the timer? I believe I read on the forum some time ago where the disc wasn't necessary with the new seal. It is only needed when the old felt seal is used. Thank you. Jim Patrick
Mark is correct. It's addition can only make trouble.
Thank you, Mark and Jerry. I'll remove it tomorrow. Jim Patrick
