Thanks for the info I do appreciate it. It looks like this 2018 is going to be quite a rebuild I put it on track and it started the home and tried to move forward and back but I could tell that they e unit lever is very loose. I already took the chassis off and I'm looking inside of it and the wiring is actually very old so I'm assuming it's probably the original wiring. I've seen where guy say to replace it, but I'm thinking if I can unsolder the connections and not break the wires I would just reuse the original wiring seeing how it's already kind of formed itself to the layout of that engine. I'll keep you all posted with pictures of the rebuild of the 2018 and if you see anything that you recommend that I should do please feel free to comment thank you very much.
