lost spark on the Honda

Mike88se · Mar 12, 2014

Brand: Honda
Model: HRM215K2 HXA
Engine: GXV140 5.0 (sorry don't have the numbers :smile

No spark. Disconnected the kill switch... still no spark. I'm just guessing but the kill switch assy just grounds the coil to kill the engine so when it's disconnected from the coil it's out of the equation and if the plug and spark are good there should be spark? The plug is good.
Time for a new coil right?

If I were to guess, your coil/magneto is probably bad.

Thanks. I ordered a new one. Right under this post was similar problems and I found a diagram that Robert@Honda posted so I guess I checked the problem out the right way.
Looks cold there!

When looking for something with the mag or spark, always isolate the engine and chassis before anything else.

How do I do that?

The mag will have two wires going to it. Primary (small wire) secondary (plug wire). Disconnect the primary wire and see if you get spark or not. If you don't have spark its a good chance you have a bad coil. If you do get spark you have a chassis problem. You should be able to have the coil tested before buying a new one to be sure, if it isn't too late. Once you buy a electrical part you own it.

Ok good that's what I did. I was thinking that would tell me if the stop switch was the problem.

(1) If no spark, try a new spark plug.
(2) If still no spark, try a new spark plug cap.
(3) If still no spark, disconnect black wire from engine stop switch and test for spark:
--(3a) If spark is good, switch is bad, replace.
--(3b) If still no spark, ignition coil is bad, replace.

It was the coil. Starts on first pull now like it used to. Still need to set that governor but not having any luck. I don't have a tach but I'd guess its running around 4 grand
