Question about Garden
When using spark plug tester, there is no fire on the left cylinder coil on a Briggs&Stratton 21 HP, OHV, twin cylinder engine. The model is 407777 and type is 0124E1. What could the problem be?
Check that the air gap between the ignition armature not getting spark and the flywheel are between .008 and .012. Also note that the engine must be producing, by Briggs standards, 350 rpm to produce spark. It's rare for an ignition armature (coil) to go out, but it does happen. If a new plug on that side and correct air gap don't solve the issue, hit me back up on it.

My name is Dane and I'll try to help you with your problem. It sounds as though you have a weak coil to me. Sometimes a coil will either completely stop producing spark or will get weak after it gets hot from a running motor. You can buy a coil tester from any automotive supply. just take the spark plug wire off of your plug and attach the tester between them. Crank the motor and see if the tester lights brightly. Be careful, the engine can still start with this installed. If the light is weak, replace the coil. I hope this helps. Thanks! Dane
