Throttle problem

[LH Lead-Foot]

Very interesting. The last four digits of the part number. OK, now I know. Thanks. A kind of short hand used everywhere. I am trying to catch up with the "Lingo".

I am so old that the high school brought a Beta Max, my younger brothers first truck had scoops on the connecting rods to get oil, no pump or filter. Air cleaners had a quart of oil to screen dirt, June bugs and other debris. The phone was wood and the operator who connected the call, was named Beulah. Oh my gosh, I just realized perhaps I was in Mayberry with a kid called Opie live on the other block!
