Snapper mower Briggs engine

[Stoney55]

I have a snapper mower that has no fire at this time. I recently replace the flywheel key and it worked fine a couple times. This morning I went out to mow and nothing. I checked the ohms of the spark plug and it seemed to be fine. Still no spark, so I replace the spark plug with a new one, no change. I watched a couple videos and it told me to check the coil ohms with a multi-meter I did and it was around 6500ohms. I was reading that that was too high a resistance. I also call one of the local repair shops and he told me to disconnect the kill wire off of the coil and see if it would start, it didn't. I am at a loss at this time. I am pretty sure the fuel is good, but not 100% positive. I am just wanting some opinions on what to do next.

If you unplugged the wire from the coil itself that means you had to take the air shroud off..... Right ??

If you didn't have spark after that it means the coil is bad.......

also the spark plug wires can arc thru to the cover. Just replace the coil - that is the easiest solution. Check to be sure that the kill wire isn't grounded but it sounds like you have no spark even with it removed.

If you removed the kill wire and still had no spark, replace the coil. Doing resistance readings on today’s coils doesn’t tell you much, as they have CDI pickups which can’t be tested.

monkeys can read . They have no understanding of what they read and apparently monkeys can now post videos on U tube also with no understanding of what they are videoing about.
A coil has 2 sets of windings + a hall effect trigger chip.
You can measure the resistance of the secondary windings ; laminations ( ground ) to the high tension spark plug terminal.
However you can not make any meaningful measurements of the primary windings or the trigger chip without a $ 30,000 piece of test equipment.
As this is a big for the pockets of the feeble minded who post on U-Tube you will not see any proper coil testing on there.
As coils like this have been standard fitment since around 1985 which was before most of the feeble minded ego maniacs who post drivel on U-tube were born one can only assume, like a 2 year old child they are facinated by numbers that move on a screen.
\For all but a few systems which are no longer used there are only 2 tests an intellignet person who understands how the coil works would do.
1) remove the kill wire , crank the engine and test the outside of the wire to ground , especially the push mower ones with a metal encased spark plug cap.
2) with the kill wire removed check for a spark from the conductor to ground.
For the first one you can replace the end cap is it is shorting and with the second you replace the coil.

At this point I have replaced the coil and the spark plug still nothing. I squirted a little carb cleaner into the spark plug housing to see if I got any spark then. Nothing.

Did you reset the "air-gap" on the new coil to specs ..??
