“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?
