“Total” timing isn’t. It’s a drag racing term, that has stuck, but is misleading because race engines do not include vacuum advance. Ignition...
48° - 52° BTDC at steady highway cruise is typical for many overhead valve V8. The only practical mechanism to get all around driveability and...
“Wintergreen oil” is actually a synthetic. It isn’t used to make it smell good, it is one of the best penetrating oils around. Stuck piston rings...
Keep in mind when using an O2 sensor "stoich" is a theoretical number, it isn't actually seen very often. When an engine is under acceleration...
There is a technical reason somewhere why the spark output is weak, make sure the ground cables are fresh, of sufficient gauge for a 6 volt system...
Measure the voltage drop across the cables and ground connections under load. If there is corrosion, or loose connections, undersized, or old...
Yeah, make sure you're running the stock heat range plugs before trying to look at jetting. Don't ask me what "stock" heat range is on a...
Have to "curve" the fuel supply too, when tuning, it's possible to be excessively rich at idle yet lean upon acceleration, or too fat at cruise...
There was flash flooding in Death Valley the other day - you know the Mojave desert. Like Meth Gators, didn't have that on my 2022 Bingo card
That's one reason why the runout spec is important, the commuter needs to be almost perfectly concentric, good bearings &c, or the brushes can...
You re-discovered why hot rodders ditched generators just as soon as possible. I wasn't there but I would bet with any serious high speed work the...
Coffee and cigarettes may eventually kill me. But in the meantime, they keep me from killing other people. So...
Years ago, somewhere in Minnesota (I think) our family stayed at some rural motel on vacation. I was maybe 8 or 10, my brother about 16. They...
"about" 4 different Radiation detectors? Unless you ingest the gauge it won't hurt you. I'm sure you can find something to worry about these...
Have set and adjusted a gazillion tapered wheel bearings, but never the ball bearing type. Are they more difficult to adjust?
Nobody makes car radio tubes though. There is still a demand for audio output tubes, rectifiers, and some signal tubes like 12AX7. The Stereo...
Tubes for car radios are plentiful and cheap. It's rarely the case that they actually need a new tube. The problem is, there isn't much to listen...
Car radios were expensive in those days. Government fleet vehicles purchased from Ford and others, didn't have radios for that reason. Such...
In the .mil we used a lot of different stuff, the sheet metal guys used to use a Hysol product on rotor blades that everybody universally just...
Patience really helps with penetrating oils. Had to remove the manifold studs same as you, except on the Y-Block. They were reefed in there good....
Plastics. Think I heard that in a movie once
In the 1970s, I thought the 1950s cars looked really, really old. And that was only 20 years prior.
Romex, masking tape, extension cords. What's not to like?
He said he wants to get rid of the 6, and, he's asking for opinions. I think he's getting good advice overall.
Right, the standard contact point ignition dwell is a compromise, because it is fixed but the engine RPM is not. So the coil actually tends to run...
"Don't do that!" (Ask me how I know)
It's also possible that the ignition coil is at least functional, but the magic smoke has been let out of some other component or gee-gaw.
It might be a little lame, but a 10k mile survivor, a "true barn find" I'd leave the 6 in it. How about a peek under the hood?
Right, I was going to mention that. For noise suppression or RFI it would be connected to the + or pos side of coil to ground.
The way I understand it, and I could be wrong, while there is a voltage reduction with a ballast resistor installed, what they are really doing is...
