'68 250 SL - Hard start...lurching/lunging/sputtering engine??????
My SL has sat for about 9 months w/just some occasional start-ups.<br> <br> The engine was totaly rebuilt in '94, and has about 2500 miles on it since. Compression on all cylinders is high and all are even, as tested about a year ago. The engine usually starts up, is a bit rough, but settles to idle after you run it for a while.<br> <br> However, it took about 2 minutes of constant cranking to get it started recently. Then it kept stalling. I got it going again, but it felt like the engine was lurching and lunging, and could not stay running unless I put the gas down at least half way, and had it at 3000+ rpm.<br> <br> The radiator was flushed last fall, and the collant, oil levels are fine. The car will move under its own power, and is mooter in neutral.<br> The only thing that has happened, is the rubber ring that holds the muffler up at the back of the car broke, and the muffler was hanging down for a while. I attached a ring to hold it up for now. But, I am not sure if the muffler pipes or manifold connectors might have bent or twisted causing a problem with the exhaust output.<br> <br> Any guesses welcome....is this lunging/lurching a sign of a bad fuel injection pump, water pump, fuel pump, bad gas???<br> <br> Thanks!
