Default Lauson TLC 351

I found a nice little Lauson TLC-351 at an auction this weekend. I had to buy all the contents from the 'south wall' of a shed to get it but didnt pay much so am pretty happy with what I have.

Its similar to the other 351s I have found here but still thought I would share some photos of it. I am assuming its military surplus - looks military surplus to me anyway. Serial number is 4-35784.

Its a cool looking engine and I was pretty stoked that I was able to add another unique Lauson engine to my collection.

It does have spark but I have not tried to start it yet.

I do have one question - what is the plug right behind the exhaust for?

I modified my original post and changed the model to be correct - I had mis-read the model number - I must be going insane - I swear it said it was a TLC-331 but not finding any information about it made be double check. Its a 351 - sorry - so its mostly the t same as the other 351s people have posted photos - doesnt have the big tag on the flywheel cover and missing the air filter.

Sorry about the mistake, I need to get some glasses.

Plug behind the exhaust elbow is for the crankcase breather. Screw in for transport to keep from spilling oil if engine is tipped.
Be watchful of the fuel pump. The diaphragm will probably be quite old and may leak (or actually pump) gasoline into the crankcase.
Good find!. I have a couple of these. One in the original Military case with accessories - Starter rope, exhaust flex pipe and muffler.

John, would you happen to have some photos of the original military case and accessories? Be nice to re-create as much of the original engine and accessories as possible. Wonder if the ratty rope with red handle that came with mine is original.

Managed to get close to my Mil Lauson today.
For some reason, it (the ENTIRE it...) got painted aluminum silver. Pretty good job of covering EVERYTHING!
This engine did not come with any accessories - Or they would have been painted too. I acquired another one like it in original colors, but the case was beyond saving. Fortunately, it had the accessories with it. Don't know what all came with it originally, but I got a starter rope (dry rotted), a length of fuel line, some flex exhaust pipe and a muffler. Flex pipe has a bayonet connector for the fitting on the engine.
