As title reads. I was using it, it was running great, shut it off and set it down. Picked it back up 10 minuites later... No spark.
- No spark with new or confirmed working spark plug.
- Ignition coil resistance is within spec
- Ignition coil gap is good
- Confirmed continuity between plug and ignition coil, at resistance spec
- Switch wiring inspection passed
- Switch inspection passed
- Tested it while bypassing the switch anyway, nothing
- Magnets feel strong, but I don't know how to properly test them
- I've also been shocked a few times while pulling the chord, whatever that means

The coil has a small bit of rust on the top, and the magnets are ever so slightly browned. Maybe 2% brown colored.

I'm at my wits end. Please help.

Try it with the kill wire removed from the coil.
If there is still nothing at the plug, try a brand new plug.
Some of these small engines are very sensitive to the grade of the plug and in particular to weather they are resistor or plain.
The other thing that happens is the lead goes bad.
Most are a screw in fitting then potted to prevent water getting in so you can dig them out & replace them.
try pulling it in a very dark place ( opps that did not come out well did it ).
Watch the wire and see if you get little flashes on the outside.
What happens is the spark runs down the wire core to the cap then crosses over to the outside of the lead and runs back to ground out at the coil.
This is a lot more common than many would believe

I pulled out the kill wire, nothing. I pulled the plug in the dark to look for spark along the wire, nothing there either. The plug is new but generic. Do you think I should order a new NGK plug and try again?
