“Gasoline-powered leaf blower?”
Gasoline power tools can go with checked baggage if they are purged of fuel and vapors but the tool itself has to go in checked baggage, not a carry on.
You’d be surprised what people have tried to walk on with.
5. Power tools
Perhaps, not so surprising, If you are a jet-setting carpenter or plumber, check-in bag fees will eat into your income, as you are not permitted to carry on essential tool bag items. Power tools, including drills and drill bits, and other tools that are longer than 7 inches, such as screwdrivers, wrenches, and pliers, are not allowed on a plane carry-on. So a leaf blower and chain saw, two items that have been attempted, are not going to get past the TSA.

I would suppose, from a safety outlook, those tools carried on in a passenger cabin space might get used to harm fellow passengers or to breach the integrity of the pressurized cabin in flight.
