Slant won't start!!?!!?!?
Compression-I have an old style gauge (push-in) What exactly am I looking for?
Forget that thing, almost impossible to use on a slant. You need one that screws in
You can actually get "some idea" of whether the cylinders have compression by simply screwing one plug at a time into each cylinder, cranking the engine, and listening carefully to the "thump" when compression hits.
If no hard "thump," no compression. If one or more cylinders has no "thump" then that one is dead
Check spark AT one of the plugs. Do this after all plugs are back in and hooked up, and use just one plug out, grounded to the block. The reason you want the rest hooked up is to prevent crossfiring.
Inspect the cap rotor for grease, dirt, moisture, cracking/ carbon tracking, etc.
Also inspect the spark by using a grounded probe, holding it near the top of the coil tower. YOU MUST use the ignition switch for this test, so you need two people
