Slant Six Points Ignition Trouble

NEVER leave the key on "run" for very long when engine is stopped. Points must be low resistance. Most any old "dwell/ tach" has a points resistance scale. I'd have to look this up seems to me you want less than 1/2 volt across closed set of points with key "in run."

Folks above are right--you must have a good "functional" condenser / capacitor to get spark. Don't discount the coil could be bad / shorted.

Make certain points are actually breaking the circuit. In my lifetime I've seen at least two distributor primary wires "rub raw" through the distributor hole and short the wire to ground, and still others (where "others" had changed their points) that the condenser lead/ insulator/ etc was grounded at the points

I NEVER used to set gap--only by dwell---this keeps the possiblility of an oily feeler gauge out of the mix, and is way more accurate. Set dwell / gap before timing. Points gap affects timing.

When you check spark, use the key to crank and not by jumpering the starter relay. This is because in "start" with the key, you are bypassing the coil resistor and it gives a hotter spark. To check, "rig" a spark gap device with a solid core coil wire Should get at least 3/8 nice snappy hot blue spark and typically more like 1/2" long
