U can only check the primary side,not the secondary side. Had same problem, changed coil and it worked, but its a crap shoot. If u have problems check ur points first, this is a mojority of the problem!
The coil is under the cowling on top of the motor where the flywheel is.

You can check the Briggs and Stratton website for the exact specs for you engine number. OR Most people use a standard business card between the flywheel and coil. That works fine. Just line up the coil flanges with the magnet part of the flywheel and the put the business card between them. The magnet will hold it in place. Then tighten the bolts holding the coil and you are ready to go.
The easiest way is to use a standard business card between the coil and the magnet part of the flywheel.
0.010-0.014" is the Briggs spec
The coil gap for a Briggs & Stratton 3HP motor typically ranges from 0.010 to 0.012 inches. It's important to measure this gap accurately to ensure proper ignition and engine performance. Adjusting the gap can be done by loosening the coil screws and using a feeler gauge to set the correct distance before tightening the screws back. Always refer to the specific engine's manual for exact specifications.
Depending on year and model of motor. : You will find the contacts either under the fly wheel or there will be a pick-up on the coil.
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.
check your rotor & pickup coil
BACK emf induced in a motor's coil that tends to reduce the current in the coil of the motor. The answer should be 'back'.
You buy a coil with it on it
It is the same as an ignition coil on all internal combustion engines. It is a high voltage transformer that provides a spark at just the right time to ignite the air-fuel mixture in the combustion chamber.
