0010-0.014" and a normal business card serves as an easy to find gauge.
What I do at the shop is fold abusiness card in half . Put it in between the Coil and Flywheel. Bring the magnet around to Coil and tighten screws down. Perfect gap!
I think what you are wanting is the air gap between the flywheel and the coil . The gap is somewhere around .002 in , but if you will take 2 matchbooks take off the covers and use them for spacers between the coil legs and the flywheel . Role the flywheel around till the magnet pulls the coil in . Place the matchbooks between the coil arms and the flywheel and tighten the screws . Check the spark plug and make sure you have good fire .
Air gap between coil module and flywheel should be .010 inches.
You can use a standardbusiness card for the gap.
The coil has two bolts to hold it in position. Loosen both bolts, place a .010 - .014 feeler gauge (or business card) between the coil and flywheel, and tighten bolts. The size of the gap determines the timing of the engine.

.012" to .020"
20 thousandths of an inch will suffice. Fairly forgiving ..........loosen the coil and place a standard business card between flywheel and coil. Allow magnetic force from flywheel to pull together and sandwich card between flywheel and coil. Tighten coil. This will work fine.
On most lawn mowers there is no timing - they have the flywheel set, as long as the shear pin is in place, it will put the magnet by the coil at the proper time to fire. The points are run by the gap (you set the gap on the points) and the pin pushes the points open at the proper to fire. The only setting you have to do is the gap on the flywheel to the coil and the gap on the points.
If you are talking about a small engine such as a lawn mower, the air gap between the coil and the flywheel is usually is .015 to .020 of an inch. A piece of cardboard from a cereal box can be used as a gauge if you don't have the proper gauges.
The air gap on the pulse coil of a 1984 TRX 200 is the distance between the pulse coil and the flywheel's magnet. This gap is crucial for proper ignition timing and engine performance, as it ensures that the pulse coil can accurately detect the rotation of the flywheel. If the air gap is too wide or too narrow, it can lead to starting issues or poor engine operation. Adjusting the air gap typically involves repositioning the pulse coil to achieve the manufacturer-recommended distance.
The gap between the coil and the flywheel on a 17hp Briggs & Stratton engine is typically set to 0.010 to 0.020 inches. This gap ensures proper ignition timing and optimal engine performance. It's important to check the specific model's service manual for the exact specifications, as they can vary slightly. Adjust the gap accordingly using a feeler gauge for accuracy.
