While trying to oil my Williams PA-1 powered engine, the needle from the oil bottle fell in to the body of the engine. I had to take the front truck off to get to it with a magnetic screwdriver. I have been trying to get that screw back in to the truck, but it will not go in, I line up the screw hole with a drill bit the same size, then put the screw in, but it will not screw in, I haven't slammed it against the wall yet, but I'm getting close, why am I having this problem?
