Hi Nick,
I think most on this Forum will agree that the "HIGHLIGHT" of this "entire" Forum is to have wonderful gentlemen like yourself who come back to report what is stated in your reply no. 24.
You found the problem, got it fixed ........ and compassionately took your most valuable time to get back to report your findings in order to help other Model A owners who may encounter similar problems.
So many almost everyday Forum members contribute so much of their valuable time, experiences, and advice for FREE ....... and in many cases, some Zipper Lip Scrooge Farts fix their Model As with their FREE advice, and never take the time to get back to respond in order to help others to repair their Model As.
Just a Big Thanks for your very thoughtful reply.
