So, I have a 1969 601 that has not been started for at least 10 years now, perhaps a few more. I am hoping this weekend to get a new 6v battery, put some gas/oil mix in the tank and see if I can start the engine. I will probably buy and install new spark plugs also. Does anyone have advice for what I should do prior to attempting to start the car, or should I just give it a shot? Also, the gas tank is empty at this point, and looking in the tank there appears to be a seam that runs from front to back generally under the filler hole. It looks like there is a gap in that seam, and I am not sure if that is normal, or if that might be some sort of defect that will allow the gas to just leak out or maybe that is just the way the tank normally is. Has anyone seen that seam in their tank before, and should I be concerned about it? It might make sense for me to pull the tank ahead of putting some gas in it to see if it looks like the seam passes through the tank shell if the way the seam looks is unusual. Is it difficult to pull the tank out? Any tricks or “gotchas” about doing so? I can try to take a photo of the inside of the tank if that would help.
