This is a little 43 Briggs Model N Lever Start that I picked up recentley. I noticed it was military green below one of the gas tank straps, but as I stripped the paint off, I found it was olive drab directley on top of the original Briggs brown primer, so this use to be a military engine. After some valve adjustment, carb cleaning, etc, I had it running. The original gas tank was really beat up, and I had one in much better shape, so I used it. I'll fix the original tank as time permits. Rebuilding gas tanks is a very time consuming ordeal. These first pics, and video are of when I got it, and during the rebiuld. Although it didn't smoke, I always at least re-ring my engines. I also replaced the connecting rod as it was showing some wear, and of course new crank seals, and gaskets.
