First, let me say I didn’t even read the article, Rob, the subject was enough to spark good and bad memories about my experience with these devices, and yes, I still have the unit that damn near killed me.
First, you need one to know when the exhaust cracks open and the intake finishes closing, if you know what I’m talking about you’ve adjusted your own valves before!
Ca 1978, an 18 year old kid (who will remain nameless) was working at the Mobil Repair Center and someone came in with a nice Datsun sedan or coupe with front rotors that had broken away from the hubs (they were as thin as 45 RPM records) and the pads and their steel backs were gone, the pistons doing the only work, and it needed a tune up. The tune up is what got me in trouble, a dual point distributor and a remote start switch turned out to be a great life lesson.
Now, after working on the brakes, rebuilding the calipers, new pistons, rotors and the like (there were no kits with calipers, pads and rotors back in the day) it was time for the tune up. I hooked up the Sun machine and got the dwell set just right (dwindle, dwarf and dwell, the only three words in the English language that start with DW), I popped the distributor cap back on and hit the remote start. It fired right up, back in the day all Datsuns were stick shifts, fast idle cam engaged, 2000 RPM, ran like a Swiss watch. Problem was, it was and automatic, and it was in Drive, and yes, I was in front of it. A year of not walking and you’ll never find me again in front of a car I’m not in control of. A lesson we’ll learned. There’s a lot more to the story though you get the picture.
