Gasped when I saw all those pieces and could finally breathe again when I read you got it all back together! Whew! I have a Rocketeer 500A too! Want to get it running better...mine is unusually slow. Found a crack in the bottom of the foot pedal, so I replaced the foot pedal and wires. Still running slow. I think if I just just it more and keep it oiled it will loosen up. (fingers crossed).
