No spark is either a wiring problem ( magneto is grounded out - no spark) or the magneto is bad. Either way the flywheel shroud will need to come off - the magneto should have 2 wires - one goes to the spark plug , another smaller lead runs tward the carb- temporarily disconnect this lead and try starting it. If it starts- theres a problem somewhere in the small lead- if it doesnt, well the magneto is bad - they run anywhere from $50 and up.

It is the ignition module under the flywheel. This is easily replaced. But you may need a puller to remove the flywheel. These components can be purchased as part of a tune-up kit. I don't recall the exact price, but they are not excessively expensive. They are also not very difficult to change as long as you are somewhat mechanically inclined.
Or it could be the flywheel key is sheared.
It could be the coil, but this is unusual with this engine.
You could also check your wiring. Check the wire between the ignition module and the coil. Several models also have a wire that goes to the throttle linkage to shut off the ignition when the throttle is fully closed.
The valves would cause a problem with compression, and have nothing to do with the ignition.
The ignition is controlled by an electronic module located under the flywheel. Older models made before the 1980's would use a set of points and condenser instead of electronic ignition. It senses the position of the crankshaft. When the crankshaft is in the correct position, it signals the coil to send the spark to the spark plug. The coil gets its power from a strong magnet in the flywheel that passes a stack of metal plates. This is part of the coil assembly.

okay first off under the pull start casing there is a flywheel.
On the side of that there is a coil pack - if there is rust on the flywheel it will not make spark - I have sanded a lot of them this year to get them going again.
Also clean the 2 ends of the pickup coil itself.
This is where the spark plug wire comes from.

judging by your question alone, you have no idea what your doin. better off taking it to a repair shop before you screw something up.
no offense, but if you have no spark, what in the world would make you think to check the valves?

If there is no spark - no need to check the valves.

I had a problem with the ignition igniter and coil. Your local parts dealer can help you out. It's not the valves.

If you've left it outside uncovered, it could have gotten wet. Need to tear carburetor apart and dry it out. I had the same problem.

check the wire and power source...
Good luck,
