I have never checked a Lawnboy coil on D or F series with a meter so no clue. The easiest test on the 7268 is to remove the small grounding wire and spin the engine over. Removing the wire isolates the coil from the circuit. No spark, bad coil. Be sure the coil mounting surfaces are clean of any rust or corrosion as well as the flywheel magnets. Good luck and let us know what you find. Bill
It should read 2.5 to 5 kohms. Make sure you have a good ground between the head bolts and cylinder head. The plug grounds through the head and the head through the head bolts. Pull off two or three head bolts and clean up the surface. I fixed many no start showing spark this way.
If my math is correct, you're actually measuring 41 ohms, cuz you're on the 20k scale. To verify, drop the scale back to the 2k scale. If it doesn't read then my conversion is wrong and raise the scale to the 20k and it should read.
