I have one of these Shovels and I also have the knuckle. The knuckle runs ok, but I have a problem with inconsistent ignition and the spark shorts over the outside of the spark plug insulator. I cut the voltage back by eliminating one battery and that seemed to help some. I haven’t tried to start the shovel and may not ever. I just like looking at them. I have a real Shovelhead to run if I want and it sounds much better! Lol
