My first post on any forum, so forgive me if I screw it up.
Just a word of introduction. I haven't worked on cars for a long time. My first new car was a 63 Ford 427 and it seems that I worked on it all the time. Completely rebuilt the engine once. Does this give you a hint about my age? My only work on cars has been routine maintenance for many years now, but I still pretty well know how everything works. My project car is a 1979 450SL that has been neglected and needs a lot of TLC. This car has been sitting a long time. My first task is to fix the fuel gauge. It was sticking (technical term) before it just quit. Should my first action be to replace the sending unit? Other symptoms. 1. Very difficult cold start 2. Idles very rough then smooths out as it warms up. 3. Wants to die with any throttle advance until it gets warm, then much better. 4. Can't drive it till the engine is hot, then it runs reasonably well.
The gas has got to be bad after sitting for so long (years) and there may be water and other goo (another technical term) in the tank. It would be nice to know how much gas is in the tank before tackling that problem.
I have been searching this forum and have found a lot of useful information. Any advice that any of you have would be greatly appreciated. Tnx
