Hello ACMOC,,,, 1937 RD4 ,,, early, how does one go about changing the oil on the pony motor? Can't find the drain plug. By the way, in relation to posts I made concerning our mag and no spark. It's all solved now, the mag did have two wires one had broken off inside the black coating and after scraping off the black stuff I was able to solder another wire on and bingo, spark. I also installed a six and a half horse engine w/ a centrifugal clutch that has a recoil start so as to start the pony w/. Works great. But I need to change the pony oil...
Thank You, Doug
