No you explained it great. (That is a good point too) I have run into all types of issues over the years concerning belts.
I'm not sure of how you belts work on your Ford but in the past on tractors and equipment that used and idler pulley to tension the belt if the belt wasn't the correct for the application ( automotive type instead of one for declutching ) even though the same length and width it wouldn't bend away from the pulley when declutched and cause a drag , ( Wish I was better at explaining things ) Al
That is a great thought Ken. And I have seen that happen, that's why I don't paint inside the groove of a pulley
Just ou of curiosity, did you paint inside the pulley when you restored the tractor? That could cause it to stick to the pulley!
