Light Switch Silencer

Three views showing the shape of the “silencer”.

Door Alignment for a Closed Car

The primary adjustment when shimming the body is at the cowl. Closed cars shift like a parallelogram as illustrated by the red line. Tilting the cowl by changing the shims below it raises or lowers the doors and changes the square of the body. OBJECTIVE Our primary objective here is the final adjustment of the […]

Cleaning Dirty Spark Plugs

When the spark plugs are dirty, they demand a really good cleaning.  You can take care of the job yourself by buying a bottle of household ammonia.  Simply soak the plugs and they will emerge cleaner than sand blasted ones.  The ammonia loosens the deposits and floats them away.

Ignition Coil Connections

The ignition coil does not change the direction of current flow hence it does not change polarity.  However, there are more coils in the secondary winding inside of the coil, thus there is more resistance to incoming current flow at the secondary winding terminal, so the coil’s high voltage output to the spark plugs will be less if the […]
