I'm working on the video Al. You bet I want you to see it. The smoke system is a tank from one of my old crashed trainers with a stopper for smoke oil, a Sullivan sky writer pump, and a Sullivan gas/smoke fueler fitting in the side, and the typical tygon and neoprene tubing. I am running the smoke oil through a brass tube wrapped around the head and then into the muffler at the pressure fitting with a check valve between the muffler and the rest of the system. I have a Perry pump for the fuel. This 160 vibrates plenty to run the engine really nice with the Perry pump. I have to thank cublover for making smoke possible on this one. I also inspect the wing and fuse connections after every flying session for any signs of a problem. It' been twisted up in flight a few times. So far nothing is out of the ordinary, still looks brand new.
