Will rust on flywheel magnets will cause an ignition system to fail?
The secondary winding of an ignition armature creates high voltage but low amperage in comparison to the primary winding. Rust on flywheel magnets will cause an ignition system to fail.
Should magneto touch flywheel?
The magneto should not touch the flywheel. In fact, you have to adjust the gap between the coil and flywheel magnets so that the flywheel magnet lines up directly with the magnetic coil and feeler gauge tool.
How do you test a flywheel magnet?
Mark the magnets on the flywheel by labeling them in the position they sit with a small piece of masking tape on the flywheel. You can test the magnets for position by using another small ceramic magnet. If the magnet is repelled, label the flywheel magnet R, and if it is attracted, label the flywheel magnet A.
How many magnets does a lawn mower flywheel have?
one magnet
There is only one magnet in the flywheel. The other piece of steel is a counterbalance and may have only picked up some residual magnetism. If you’ve got strong magnetism in the one piece, your flywheel is good. It’s possible that your ignition coil is bad.
What is the gap on a Briggs and Stratton magneto?
Replacing Ignition Coils or Armatures Your engine repair manual will provide the proper gap for your engine. Common armature gap ranges are . 006 – .
How do you tell if a flywheel magnets are getting bad?
Be sure the magnet you are testing is rotated away from the magneto when testing takes place. Hold the screwdriver against the magnet, if the magnet pulls the screwdriver in, the magnet is fine. If it seems weak or does not pull the screwdriver in, the magnet needs to be replaced.
How many magnets does a Briggs and Stratton flywheel have?
Can you replace flywheel magnets?
The flywheel magnet provides an electric charge to the ignition coil, in turn sparking the plug in a small engine. If labeled carefully and close attention is paid to placing the magnets properly, they can be replaced without taking the engine to a mechanic.
