    Installed electric start

    Here are some pics and also a pic of the starter/generator I used. FYI THE WELDER I USED WAS A CHEAP HARBOR FREIGHT SPECIAL AND IT WOULDNT EVEN BURN THROUGH 1/8” tube. I’ve upgraded my welder so hopefully better welds are coming soon lol I broke the frame last week so I have some welding to do.
