IIRC it was one of Jerry Brown’s buddies who managed to become quite wealthy during the former governorship of Jerry Brown’s with his bogus PC valve scam that “Moonbeam” signed into law as the first smog control on Calif. IIRC it cost Californian’s something like $45.00 per car to have the valve cover drilled, and that thing installed to route all that smog back through the carburater.
All a scam as I recall, but since that time the pollution control scams have just become worse.
It’s how I remember it.
I lived in California when Jerry was Governor. I learned to truly despise Democrats because of Jerry Brown and Jimmy Carter -- what a pair!
