I completely disassembled a 99H which was gifted to me, and the project was side tracked by a trip out of state. I reassrmbled it from memory but I have a tiny coil spring left over. The spring is a little less that a half inch long and maybe a sixteeth in diameter. Can anyone tell me where it goes? I have found exploded diagrams but they are not enough help. I might be too dumb to own 99 so I might have to sell them off.
