Small Engines (Lawn Mowers, etc.): Spark Old 3.5 B@S Engine, adjustment screw, ring terminal


Question
Here's the answer I got from Eric and wanted to ask followup but he is maxed out at this time:

Is your new electronic coil marked "this side up"?

Dis-connect the small wire connected on the bottom of the coil and check for spark.  If the coil is mounted correctly "this side up", and you have no spark with the small wire dis-connected then the coil is defective.

Make sure the coil is mounted correctly.

Let me know what you find.
Eric

My follow up is:  Yes the new electronic coil is mounted correctly with "this side up" and "cyl side down".  The new coil came with a connector with two wires coming from it so I'm not sure what he meant my small wire on bottom of coil.  One wire is the kill switch wire and the other is the ground that goes under the gap adjustment screw which also holds the coil on.  I want to check the coil with my continuity meter so I should put one lead where the wire connector plugs in and the other at the end of the plug wire right?  If I do that then I should show continuity and the coil would be good.  If not, then the coil is bad, right?  Am I checking the coil correctly?  Thanks in advance for your help.  My meter "beeps" when a complete circuit is found.

Answer
If I understand the problem you are having is that you have installed
a brand new coil, and you still have no spark?
   If you bought a new coil, it likely had a white terminal with
two wires coming out of it, that is for your kill wire, it has two
wires so it can work on a number of setups, most commonly the
bare wire goes to a terminal where the throttle cable mounts, so
when you throttle all the way down, it grounds the ignition as well
to shut the engine off, the other wire with the ring terminal is not used, just cut it off near the white connector so it does not touch anything, or it will ground out the ignition and you will not get
any spark, if you put that ring terminal on the engine block anywhere
you won't get any spark at all.
   Also, if for some reason you have had the flywheel off, and didn't get the starter clutch tightened enough when reinstalling the
flywheel, it will shear the key.  You would still have a spark, but at the wrong time.
   Hope this helps,
