I tried to watch the video but just got a series of still pictures. Engine must be fuel injected to do that kind of stuff. Wonder how they did it in the old days with carburetors? Must have been hairy!

The engines on a -130 are turboprops.

AT-6s are carbureted and you have to pull through the loop at about 1 G or it will empty the bowl and start sputtering if you dawdle..

Jet engines to power the props. They never built a piston engined C-130.

Dear God, it is a turbo-prop. Turbine engines are always fuel-injected. Those engines are extremely powerful.

No fuel injection. The engines on C-131s are turboprops and always have been.

“...Wonder how they did it in the old days with carburetors? …” [refermech, post 12]

Fuel injection - for combat aircraft powerplants at any rate - predates World War Two.

Not all carburetors have been the same. Pressure carburetors for aero engines were developed at about the same time reduces the problems associated with zero or negative-G conditions.

For 44 years or more, small planes designed for aerobatics have been equipped with special auxiliary fuel and lubrication systems that will permit inverted or negative-G flight for half an hour or more.
