Trying to work out a fouled plug problem one thing at a time. Right now is ignition.
Read an article about plug wire and resistence.
Stated that resistance of over 4000 ohms per foot wasn't that great.
Just checked my wires and came up with 15k ohms for a plug wire about 30" long. Now I'm worried about too much resistance.
Dist is a converted point with Mallory unilte and Mallory plug wires. Coil is a Holley something.
Car ran fair to OK untill ran out of gas (typical ground problem) and then runs terrible.
New plugs (NGK) about 20 miles ago and they look bad. Fouled; not sure if oil or gas.
Want to rule out ignition and then fuel and then valve seals and then?
I remember back in school that the resistance maximum in any plug wire should be no more than 20,000 ohms. the shorter the wire the less resistance.find some dude with an old sun scope and hook it up. you can check for plug wire resistance and spark output from your coil. if you live here I would do it for you.
