Do you mean the starter will only turn if you put gas in the carb? Or do you mean that it will only RUN when you dump gas in the carb? If the latter is the case, your fuel tank is empty, your fuel pump is not working, or there is a clog in the fuel line.
Your ignition timing needs to be adjusted.
I have a 2000 Mercedes ML320 that did the same thing.The problem was the crank positioning sensor once replaced it stopped shutting down
what year is the CLK? Most known reason for that car to stall would be the crank position sensor (CKP) its located on the left (drivers side) of the transmission bell housing, and can be accessed from the top. The easiest way to tell if that sensor is bad, is if the engine stalled when it was hot/warmed up, and then would not restart until the engine cooled off. Could also be a fuel pump issue, but the crank sensor is much more common.
For some reason it is not getting EITHER fuel OR spark , so it cranks but doesn't start
When this happened on my 1999 ml 320, it was the crank shaft positioning sensor. After replacement-problem solved.
if you have a carborator, it may have to be adjusted
From what I've experienced, up to 1995, they don't have a crank sensor and 1996 and later has one. It would reason that it would be a lot of work to get a crank fitted or cut and then install a timing chain cover to accept the crank sensor. Other than this. I would think it would work. Maybe look for a kit that would do this for you. Good luck. yes but would be different wiring
fuel pump was coming on before changed fuel filter now its not is there a reason for this
No , it would crank , but if there was no power getting to the electric fuel pump it would not start
The crank angle would change the stroke. The stroke would change the volume.
you would adjust it by re-jetting the carborator
No, the car would be called a "Mercedes Benz" - 'bent' would mean that it had been in an accident.
