Do you have a model number for the engine?

are they actaully magneto or CDI on that engine? The only info I could find on a Honda 11hp vertical engine says it has Transistorized magneto igniton.


Usually a magneto engine doesn't have points, since the timing is controlled directly by the magneto location.

Engines with an alternator, use points and a coil, and usually have a battery to energize the coil. My 10 Hp Kohler has this setup. Some engines will run with out a battery but some won't, depending on the type of alternator.

From what I can find on that engine, it has an alternator style igniton with a lighting coil. The flywheel has to be installed and spinning to make a spark.

The magnet on the flywheel makes current when it passes the alternator, and charges the battery and runs lights when it passes the lighting coil.

In these systems it can be any one of a number of things that is messed up.

Make sure all wiring is clean and firmly connected.
Check all the grounds for the engine.
Make sure you don't have a shorted wire somewhere.
Make sure that the points aren't shorted to the engine. (this is common, especially on old engines where the insulators have broken down)
The coil and alternator can be tested using a multimeter, and the tests are usually pretty accurate.

If you can find a service manual for it on line it would be greatly helpful.
