Hi MoM, Welcome to the forum.. I note your mention of a degree of initial incontinence now seemingly resolved, though read no mention of flushing out the rad... might be a task worth considering..?
Also beaming up gomog.com will open the door to a wealth of reading matter on all things technical related to Morgans..
I suspect early Morgans have the potential to keep going on and on, a bit like cockroaches, when more modern kit fails... ?
