An old all cast iron flat head Briggs was my first engine. Had that same carb/tank set up as the one you have. I bought it for a dollar and fifty cents from a kid down the street when I was 13. Yup, the old T rope starter. Hey, at least the spring never broke eh? Just tie a new knot.
Put that motor in a go kart I made out of 2x4's and planking. Yup, wood. Wheels scrounged from a discarded golf bag pull. Belt & pulley drive with a groove cut in the wheel for the belt. Yup, it went down the road -
Thanks, brought back memories.
