My 1984 300D isn't turning off... I think the linkage is messed up because when I hit the stop switch it wont hardly move... I had to take a screwdriver and take a piece of the linkage off and pull up on it to shut the car off... I am thinking my shut off valve is messed up. Can someone send me pictures of how the linkage looks so I can make sure something isn't outa place causing the switch not to work.
