Briggs powered Sears.
well my dad had a old 66 custom 6 sitting out in the backyard for a very long time we got the frame ready to throw a engine on and i putting the 8hp briggs we bought a couple weeks ago on it instead of my dads 8e. the 8es engine was fine. it was my mistake that made it push oil (dumb*** me filled it up to the full mark on a hille oops). but i did change the tranny in the 8e. so my dads 8e has a early 66 custom 6 (square fendered) tranny in it and my dads other 66 custom 6 (round fendered) is getting a briggs
