I'm sure this subject has been covered in depth, but I'm new, so bear with me. I just purchased a 1998 TRX300FW 4x4 last week. Runs good (no smoke), but idles erratically. I opened the gas cap to add fuel and saw rust in the tank. Decided to check the bowl screen in the petcock. There is none and I found the petcock will not shut fuel off completely. Petcock bowl was full of rust sediment. Drained the tank as best I could, but I think sediment is preventing complete drain in normal and reserve petcock settings. Time to take off the tank. Looks like I'll have to remove the carb and check it too for rust debris. Oh well.
What have you guys been using to clean tanks and rustproof them? I have seen videos on muriatic acid, vinegar, etc. Just looking for real-world experience before I get in too deep, haha.
