I am going to call this build finished. I still have to install a torque converter and seat, but for a first go kart it was a fun build. I have to put my effort into my 2017 build contest entry and stop playing around with this one and the little Manco I bought.
My new Kart has suspension, this one does not. At 20 mph on an average rough dirt road, it want to bounce off into the woods. I am not sure how much faster it is than 20 mph, probably 25-28 max, but I am afraid it would end up upside down in the woods if I went faster than 20 on dirt.
