I recently joined this forum to look for answers, I haven't had any issues finding anything. You guys have a wealth of information here, great site! For instance, tonight my roto start quit working. At first I thought it was the one way bearing, I then realized the shaft in the motor wasn't spinning the crank. One search later, I had my crank pin removed as well as the spring. I open the spring up slightly, reinstall the pin. And guess what, everything worked! Thank you again
