Check for spark

I wanted to check for spark, but rather than do the more laborious plug-against-the-block check of the spark plugs I borrowed an in-line tester from a friend of mine. This handy tool lets you attach to one end into the installed spark plug and the other to the distributor. A light in the middle lights up when the circuit is completed. Here is a short video showing it in operation. Shout out to my son for starting the car for me while I held the camera.

It’s not easy to see on video, but the light is flashing. So I have spark on all four plugs. I also replaced the distributor cap and rotor. The old ones looked a tad corroded, and since those two parts are inexpensive I figured they might as well be changed along with the plugs.

The motor is still stalling out, so down the checklist I go.
