Hard to tell if they’re wet. 
And that’s where my questions lie. If not fuel, then what? 

Thanks for all responses thus far people

Anyone in the Vancouver BC area??

are you using an inline spark tester when checking for spark?

No, just the old fashion way with the plug held against the block. I’m getting multiple sparks that way..

It harder for a plug to fire under cylinder pressure. The tester will allow you to see if the plug is firing under cylinder pressure.

Grab your volt meter and check something.
Screw the spark plug into the block.
Meter on DC V.
Key on
Kill switch set to run
Red probe positive battery post
Black probe to negative battery post
What is your voltage to one decimal place (ex 12.5v)?

Move black probe to the hex nut of the spark plug.
What is your voltage to one decimal place?

Turn off bike

We're checking that the two voltages are close which will verify that the plug has a good ground when installed in the bike.

It doesn't seem you have a fuel issue as the starting fluid should have fired the bike.

Something is up with your spark, timing or valves.

If the plug is sparking outside the head, it will spark inside.  I would look for the problem somewhere else.  Maybe spark timing?

If your mixture is too rich, starting fluid will make it even richer and it will not start. 
Turn off the fuel and drain the carburetor bowl. Now will it fire with starter fluid?

How does one check the spark timing? 

Purely a question, not suggesting you’re wrong, but why would the timing change or be disrupted if I didn’t remove anything other than the starter? 

Thanks

I’ll give it a whirl this morning. 

I did replace the 11 amp battery with a smaller 3.5 to run the lights.

You would be amazed how many posts there are about perfectly healthy bikes that went into the shed and developed all manner of problems - I suspect there are naughty garage fairy's at work all over the world

Very close readings.
11.24 both terminals and 11.16 on the spark plug.
