How far should the magneto be from the flywheel?
010-inches or between . 010 and . 014-inches. Rotate the flywheel so that the flywheel magnets line up directly with the magnetic coil and filler gauge tool.
What happens if the gap between the magnet and magneto is too small?
In the diagram on the right, we can see a magneto ignition coil and a flywheel. The air gap between the coil and the magnet on the flywheel is vital if we are to produce a good quality HT spark. If the air gap is too small, the flywheel can physically contact and damage the laminated iron core of the ignition coil.
How to adjust gap on armature Magneto and fly wheel?
Rotate the flywheel so the magnet is away from the ignition module bosses. Install the ignition module to the bosses on crankcase, using the hex. Flange screws. The directional arrow (on some modules) denoting proper flywheel rotation must be up. Move the module as far from the flywheel/magnet as possible. Tighten the hex. flange screws slightly.
How can I tell if my flywheel magnets are working?
At 3000 or so RPM the spark will occur between these marks. To check this you must use a timing light with the engine running OR with the engine off, physically turn, and jam in position, the advance unit. Then check it.
Is there an air gap between magnet and FLYWEEL?
This old of a motor like yours requires a tecumseh cut away flywheel to adjust air gap since there is no other way to read the gap between the magnet and coil legs since it’s all internal and you can’t see it.
Where do you find the points wire on a flywheel?
Let us start from the beginning. Pull the Flywheel cover and find the points wire that comes out of the top of the crankcase. It is usually a black wire with a white strip or a solid black wire but not always. Check your shop manual. When you find the points wire connect a Buzz Box to it and turn it on.

Is it necessary to buff a magneto flywheel?
Yes, buffing the flywheel is quite silly, as the rust on a flywheel doesn’t give a chit about some light rust….. But the ignition coils need a good clean ground to function properly, and that is where the vanguards need looked at….
How does a magnetic flywheel work on a lawn mower?
When the magnetic flywheel passes the ignition coil, the magnets trigger the coil to produce a charge that is sent to the spark plug at just the right time, which in turn fires the fuel in the engine cylinder to produce engine horsepower.
