I thought I'd seen everything

Half a butterfly valve from the carb wedged under a valve. Can't imagine how that thing got sucked up thru the manifold and into the runner of the jug on a 1915 ALF engine.

Wow, that is a heck of a large butterfly! Big engine needs big amounts of air and fuel I guess.........

Is it off one of those gigantic cast iron Strombergs? Must have made for an interesting running problem........customer say it was making a little noise........maybe hard to start? Fuel mileage must have went from four mpg to three!

Engine was frozen up due to a crack thru the water jacket in a different cylinder. Yes, one of those big Strombergs.
