Expert:  Rick replied 4 years ago.

Have you checked for spark? When was the last time the valves were adjusted?

 

Customer: replied 4 years ago.
how do you check spark?
Expert:  Rick replied 4 years ago.

You can check for spark by removing the spark plug from the engine, putting the coil wire back on it and placing the plug in contact with the metal block. In a shaded or darkened area you should see a nice blue spark. Be careful and do not to touch the plug or wire while doing this, so you don't get an unpleasant shock.

 

Let me know and we'll continue.

no spark

 

Expert:  Rick replied 4 years ago.

Then you probably have a bad ignition module, but let's make absolute sure by:

 

  1. Trying it with a new spark plug
  2. Taking the grounding wire off the base of the coil to eliminate the possibility of a bad switch or damaged ground wire
  3. Clean the mounting points on both the coil and the block with a bit of sandpaper to remove any corrosion

 

If you do this and still do not have spark, the coil will need to be replaced.
