Which jeep engine do I have (pics)?

The L and the F refer to the locations of the valve train in relation to the pistons. A flathead engine (like yours) is an L head. These engines were later redesigned for more horsepower by moving the intake valves into a larger head, which makes the intake flow more efficient. These were known as a F head.

Some guys get mixed up because of the F head and Flat head. They are not the same engine.

Long and short, yours is an L head (also known as a flathead.)

Thanks for clearing that up. I ordered a new carb and choke cable and a new gasket for the carb. I bought the gasket with the little triangle shaped thing. What is that for and is it needed or should a guy just use the gasket that comes with it?

Is your Jeep a Hotchkis 201?

I would not know what a hotchkis 201 is? All I know is that my GPW was used on an air force base to guide planes around the airport. It is called a "follow me" GPW. It had a big sign on it that said "FOLLOW ME" and the pilots would follow it. I guess thats why it is in pretty good shape for being 68 years old.

The original carb for a GPW/MB was the Carter 539S made in St Luis. Still available here in UK as new or rebuilt.
The Hotchkis is a post war French made Jeep after they took over the tooling and licence to copy the war time Willys and Ford Jeeps.
I think that triangle affair that fits at the carb flange is simply to aid the mixing of the fuel air intake. Ron

I bought that little deal for my carb. I hope it runs better.

Hi

That carby is a Solex PBI ..used on various European cars ( and Hotchkiss Jeep ) and a variant of it was used on series 1 Land Rovers and Standard Vanguard etc. Those carbies are currently made in India for the US market where many Jeep owners replace the Carter with a Solex PBI..
