No one has a problem until they do. It usually happens when one floods the engine, either cold or hot, and opens the throttle, then turns the prop thru cold a few times to clear it, then forgets to bring the throttle back to idle, makes it hot and big trouble occurs. It happens to pilots well versed in these type airplanes,often those with high time in them. Let me reiterate, when I started flying there were many people who would give you a prop. Today almost no one will as they do not know how to. It's a stupid arguement. It's also true that often someone try's starting it on asphalt with no chocks and no place to tie the tail down. Asking for big trouble. Bye bye. ( I weigh 195, 6 ft. And flew them a lot)
