You more than likely have a valve cover gasket leaking. You can try tightening the bolts holding the valve cover in place to 20 lb/ft of torque, (do not over-tighten) and see if that stops the leak. If not, you will have to replace the gasket.

How do you remove spark plugs from Mazda 323?

With great difficulty unless you have the correct socket! I have dozens of spark plug sockets for many different types of plugs and none of them will fit down the hole in the cam cover, you need the special Mazda socket that fits in the hole. Really silly the way they've done it, you have to spend about seven quid on a socket that you'll probably use just once!

How do you test a magneto coil?

If you have access to a spark tester, use it. Otherwise, remove the spark plug, reconnect it to the spark plug wire, and rest the tip or threads on a good engine ground, AWAY from the spark plug hole. Attempt to start it, and watch for spark. If none, replace the spark plug and try again. If still no spark, the magneto coil may be faulty.
