It's embarrassing to admit this one has me stumped. My mower with a Briggs 19.5 HP mower (31P6 77 0144 B1) suddenly refused to start. It's nine years old so it's no surprise it might need attention. After confirming air, fuel, and fire, I pulled the blower housing and found the flywheel key slightly dented, so I replaced it. New fuel filter, drained and refilled the tank and carb with fresh gas, still nothing.
Pulled the carb and found a couple of bad o-rings, so I put in a kit. No success. When attempt to crank it, even with no choke, the plug gets soaked. The solenoid operates but it looks like it is no stopping the flow of fuel when the key is turned off. When I remove the spark plug and manually turn the engine, I get way more gas ejected than expected.
I've been at this almost a week, so I someone can jump start my thinking, I'd really appreciate any help I can get.
Thanks in advance!
