Do you recall the color of the spark? A yellow/orange is a weak spark

It was a no go when I tried to start it just now. No catching at all.

If the spark is yellow mostly, how do I get it to be blue?

Try closing the gap a bit.

Oh, when you test a spark plug like this and ground it to the block -
always make sure you have a shinny surface. Use good metal and not a
painted surface.

I'll buy a new plug, but, how do I fix a weak ignition?

Find us the online manual/link for the engine.
