I have an 1980 450SEL which I bought new. I have driven it less than 17,000 miles. Recently, I had not started the car for about 8 weeks. When I start it, it starts immediately (I have a new battery) but dies almost as fast. I would like to get it started so as to take it to the dealership as the car is in a garage which is difficult to get to with a tow truck. Any suggestions? Should I try a carburator cleaner in the in flow?
