440 timing pinging and popping thru exaust

It seems I owe 73 an apology re post 38.
I misread it, and took it to be an insult to RRR. But from the gist of this rather rambling thread, I have concluded that it was not, but rather, seems to be some form of camaraderie.
So 73AbodEE; sorry.
And to any one else whose toes I may have stepped on, also, sorry.
