What is the gap between the magneto and 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.
How do you test a magneto?
Manually set the dial or button on the meter to the 40 k range. Do not use auto ranging, as it is unreliable with a magneto. Touch one probe tip to the engine block and the other to the metal clip inside the rubber casing which normally attaches to the spark plug. Readings are given in thousands of ohms, or “k” ohms.
Why is the ignition module air gap so important?
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 big, the magnetic lines of force (magnetic flux) tend to splay out into space, and do not act on the windings of the ignition coil, thus causing the coil to produce a weak spark.
How big is the air gap in a magneto ignition system?
Air gap is meant to be small — typically a few thousandths of an inch. Air gap is a fairly critical adjustment in small engine magneto ignition systems. The smaller the air gap, the better will be the magnetic coupling effect between the flywheel’s permanent magnets, and the coil armature’s poles.
How big is the air gap on a Honda gxv120?
As I understand it, you may get a spark at a lower cranking speed with a relatively small gap, and the larger the gap the later the ignition timing, but it just isn’t a very sensitive adjustment within reason. For the GXV120, Honda specifies a gap of 0.4mm plus or minus 0.2mm.
How big is the air gap on a small engine?
Small Engine Magneto Ignition Air Gap Adjustment. ‘Air gap’ here refers to the space at the rim of a small engine’s flywheel between the flywheel’s embedded permanent magnets, and the poles of the adjacent ignition coil’s laminated armature. Air gap is meant to be small — typically a few thousandths of an inch.
How does a wide air gap affect ignition timing?
A wide air gap, say .030″ will ever so slightly retard the ignition timing as the magnetic field takes longer to build within the coil windings.”
How do you adjust the air gap on a Honda gx160?
IGNITION COIL AIR GAP Adjustment is required only when the ignition coil or the flywheel has been removed. ①. Loosen the ignition coil bolts. ②. Insert a long feeler gauge of the proper thickness between the ignition coil and the flywheel. Both gaps should be adjusted simultaneously. ③.

What are air gaps on Briggs and Stratton?
Briggs & Stratton Ignition Armature Air Gaps The amount of clearance between the flywheel magnets and the ignition armature. The ignition armature is also referred to as ignition module, coil, laminate, magneto. Model Series Type Armature Air Gap ( in. ) 60000 L-Head Aluminum/Cast Sleeve Single Cylinder
