Someone mentioned it on another thread but it fits here too.
Mothballs in the gas tank. Supposed to make more power. I always thought it was a myth perpetuated in teenage bench-racing sessions. Anyone ever use these?
hey old farts i know how to hone out break cylnders(forgoten art), turn drums, adjusting valve to rocker with a feeler gauge, valve lash, bring the battery inside and not so much the 100 watt shop light but a electric blanket works well on sub zero nights . o yea the card board to cover the radiator for more heat in the winter.
Does anyone know of any procedures that were commonplace on early autos that we no longer perform any more. I'm thinking of things like:
1. Breaking in engine oil before driving any distance
2. Polarizing a voltage regulator on a generator equipped electrical system.
3. Setting a choke on a carburated engine before starting.
Any others with details? Anyone care to explain the ones I listed?
I don't know about breaking in engine oil but I can answer the others.
To polarize the generator, simply make a short jumper wire to short between the battery (b or bat) and generator (g or gen) lugs on the voltage regulator. Just a split-second or a spark is required, so simply tap your jumper wire onto the lugs and pull them right back (“Gen” equals “Arm”)
To set a choke on a carb. You need to press the accelerator pedal to the floor and release it, then adjust the choke plate so it closes nearly all the way. This is best adjusted in cold weather when the engine is also cold. Obviously you can't adjust it properly with a warm engine.

I used this method to adjust the solid lifters on my 70 Boss 302.
Another interesting option from way back were gas line heaters.
