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
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.
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 .
