1973 Mercedes 450 SL
rough running
Alright, first post, Sometimes when the engine in my '73 450 SL is hot, just been run on the highway or something where the engine gets particularly hot, when i start the engine, the engine speed will not even register on the tach, run very slowly and make a huge stink. But now the interesting part, if I rev the engine up to 3.5-4.5K it will spool down and run perfectly.
