I thought it had died at the lights. Only heard the car beside me. The antenna barely swings at idle, like two millimeters…
I found the the engine with the intake cam a hair misaligned (too my much valve overlap) but not far from factory. Age or PO, not sure. I set the engine with the exhaust cam advanced by the width of the notch. I knew this worked and was supposed to help idle so I didn’t bother going back and getting it spot on.
It pulls well up to 130 kph, and sounds better. And it doesn’t nearly stink as much as it used to. I‘m sure there is not much of a disadvantage.
If anyone is willing to try that some day, please report. I want data.
