Experienced gardeners share their insights in answering this question :
Most magneto coil to flywheel are set at .010 to .012. The actual setting depend on the manufacture specs. With the addition newer timing circuits in these for spark advance you should set them the factory specs.
Now if it a Briggs and Stratton Engine you can get by using a standard business card for setting the gap but some the newer chainsaws you can’t get well timing spark.
How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
As long as it is not less than 0.30mm, it will be OK. If the gap is too great, the engine may not start as easily. If the gap is too small (< 0.30mm), there is the risk that the coil and flywheel might touch as the flywheel heats up and expands when the engine is run.
Common armature gap ranges are . 006 – . 010″ and . 010 – .
What should the spark plugs be gapped at? When running a magneto ignition it is not necessary to run a wide spark plug gap due to the longer duration of spark. We recommend that you set your plugs anywhere from 0.018” to 0.025” with the closer gaps being used for higher RPM applications.
: an air-filled gap in a magnetic or electric circuit (as the space between the field-magnet poles and the armature in a dynamo or motor) : wind gap.
A worn or excessive gap will cause an ignition coil to work overtime, using more voltage to bridge the gap and create a spark inside the cylinder. This increase in voltage stresses the internals of not only the ignition coil but, in certain circumstances, the driver of the ECU.
If the gap is too small, the air can become ionized. When this happens, the air changes from a good insulator, to a good conductor. This is what allows an electrically charged thunderstorm cloud to suddenly release large amounts of current in a lightning strike.
Spark Plug Gap for the RJ19LM is . 030″.
Many think the larger the gap, the better. However, if the gap is too large, and the ignition system can`t provide the voltage needed to spark across the gap, or turbulence in the combustion chamber blows out the spark, misfires will occur.

How to replace ignition coil on asthil 029
Coil should be held on the saw with 2 torx t27 size screws. These will resemble a star. Remove the 2 screws, lift out the coil. The small wire should be attached with a spade connector, slide the spade off with needle nose pliers. Disconnect the spark plug wire from the spark plug, & thread it out of the saw as you remove the coil. Assembly is reverse order of removal. For clearance, loosen coil screws, alike coil away from flywheel
Coil gap What is the coil to rotor gap for a Poulan Pro 285
Remove the plug. Place a business or index card between the coil and flywheel. Rotate the flywheel until the magnet holds the coil tightly against the card, tighten all fasteners. Rotate the flywheel until the magnetic attraction eases and remove the card. Rotate the flywheel through a couple of revolutions and ensure nothing drags or contacts the flywheel. HTH
I believe I have a 18hp B&S engine, and the magneto has gone bad twice…It seems to only last about a month, any ideas?
Well hard to say without seeing it, but did you leave about 0.010″ gap between the flywheel and the magneto? Or have you been turning over the engine with out the spark plug wire being hooked up to the spark plug?
