You can also check it with no tools, just by holding a spark plug wire near 
a good ground and looking for a fat, blue spark.  If you're not much of a 
mechanic, you can just hold the wire and crank it over.  If there is a good 
spark, it will be painfully obvious.

You can buy inexpensive spark checkers, but here is one I made many
years ago
<http://public.fotki.com/mikesloane/tools__equipment/ignition_tester.html>.
In fact, I dug it out of my tool box just the other day and used it on
the engine of an International 184 that refused to start when hot. I
hooked it up and spun the engine with the starter and got a nice blue
spark, and that eliminated 1/3 of the alternatives - you need three
things to make a gas engine run:
1. spark
2. compression
3. fuel

If you have spark and fuel, then you start to look for compression
problems - burned valves, sticking valves, bad/broken rings, etc.

Chasing this kind of problem can be very frustrating, but you just have
keep eliminating things, starting with the easiest/cheapest, and working
down the list.
