Won’t start

The rest will evaporate. If not, then will after first warm-up.
The question is how did all that gas get there?

If past the rings, then it will have washed away the oil in the cylinder and you will have very little ring-seal left, and so very little compression.
But that's not THE big problem; your engine will start with as little as 30 psi.
No!, the big problem is that without a ring-seal, the falling pistons cannot create the low-pressure area, for the atmosphere to fill, and so the engine rarely starts. It cranks and fires just fine, but yur lucky to get popping and farting.
There is a simple cure tho, just pull the plugs and squirt some oil into the cylinders, bump it over a couple of revolutions and wait say 20/30 minutes.
Then pump the excess oil out of the cylinders, making a huge mess if you don't plan for it. Crank long enough, without spark,and with the choke blocked-open to prime the engine's oil circuits; and then re-install the plugs.
With the carb now fixed,not leaking gas down into the intake, and the choke working properly; it should fire right up.
But if it didn't get there past the rings, and the gas is not traceable to the carb, then replace the fuel pump.

Good luck
