Just did 50 some miles today in a L76 in 93* heat put some 93 pump gas laced with ethanol. And the car ran great. So not sure what problems I was suppose to have

The problem with ethanol gas at these temperatures is when you stop for like refueling the carb will get heat soak, be hard to start and stumb and cough until it clears the condition. You likely just drove your 50 miles and we’re done. Once the engine cools the condition goes away.

Great info! This is the experienced knowledge I’m seeking. Appreciate the straight forward lesson learned!

The engine is NOT flooded and that is the proper thing to to to unload a flooded engine.
Usually you are better off holding it about a 1/3 down until it starts and then feather the accelerator to keep the engine running until the condition subsides.

This is NOT a problem with non ethanol gas like the OP has found for his car.

Actually, percolation can cause a flooded condition - mixture to rich to ignite, so using the flooded engine starting procedure is correct. One probably doesn't need to hold the throttle to the floor, but why not?

NOPE.
I generally follow Dukes’s thoughts on most thing but not on this. Heat soak causes the hot engine to boil the fuel out of the bowls so it is the opposite of a flooded engine. I have tried every conceivable acceleration movement and have found the 1/3 method the most effective.
