2013 TroyBilt Pony. Briggs & Stratton model 31c707-3026 G5, 17.5hp. Bought used April '19. Changed oil, replaced spark plug and fuel filter at that time. Ran fine until last week. Used it for about 20 mins, stopped to empty grass catchers and wouldn't re-start, no matter what.
What I've done:
1. Replaced spark plug, although the one from April looked good.
2. Used an ignition/spark tester - saw ZERO spark no matter how I set the tester.
3. Ordered new coil. While waiting for new coil to arrive used a wire wheel to clean rust from flywheel and magnet.
4. Replaced Coil/Magneto. Briggs & Stratton website said the original coil was replaced with a model #595304 coil, that's what I installed.
5. Installed and gapped new coil per instructions.
6. Tried starting the mower. The engine ignited for about 3-4 seconds then shut off and NEVER re-fired.
7. Used ignition tester again. Consistent spark seen at the tester's gap size shown in the pic. I do not know which lines on the tester's Small Engine (SE) section represent an approx .30 gap. NOTE: When I adjust the tester any farther out than pictured the spark becomes intermittent.
Fuel (ethanol-free) is fresh, no water.
Does the tester's spark gap shown in the pic confirm that now the coil is working properly?
Please, what's next?
Thanks, Ken
