Single cylinder or twin engine? Check for spark at the the spark plug, by removing and grounding plug to the metal of the engine with wire attached, and see if you have spark when cranking. If this is Honda twin, it has a stop diode that can go bad and kill spark to both cylinders.
Honda model number?
You have spark and fule and it would not fire with starting fluid? How did this begin? How many hours on the engine?
This is a timing belt engine and if it does not fire, the timing can be off from a slipped or broken timing belt . Remove the valve cover and see if the valves are moving.
And a GXV530 is a twin engine !
I would do some more checking first, like remove the valve covers and check the valve operation. If valves are not moving, the belts are broken. The belts are not an easy fix, and unless you are good with engines, I would not suggest you try it.
With a service manual , you could do it. At a mower shop figure it will be $500 for repair.
One thing to try, would be to remove the spark plugs, and put a teaspoon of fuel direct into each spark plug hole, re-install the spark plugs and see if it will start for a few seconds. If it does, the carburetor is not letting fuel through. It it makes no attempt to start, then the timing is likley problem
No spark! Ok,did you remove the kill wires from each coil and test? More likley the kill diode is bad, than both coils!
Some where up the wire, they connect with the diode harness, unplug them there.
Yes, each coil has a small wire, that is the kill wire.
Did you check both coils / cylinders for spark? I have never seen a magnet lose it's magnetism. The one coil you checked may be bad, that would explain why one spark plug was dirty.
No spark with kill wires removed, has to be bad coils.?? Seems odd that both would have failed? How did this all start? From that, I would replace both coils and the stop diode, as it may have let voltage go to coils and ruined the coils. And remember these coils are right and left, so can not be swapped.
