I've got a 1986 190D 2.5 non-turbo(201.126 602.911). I just finished putting new seals on the delivery valves and cleaning/pop testing the injectors.
When I got the engine started, it slowly climbed to 2500 or so rpm, would not come down, would NOT turn off, and the emergency stop lever under the hood did not work either.

Is it possible that the delivery valve copper washers are put in wrong? Would this cause the out of control running? They were used. I could have put them in upside down. I've pulled all the vacuum hoses trying to get it to stop, to no avail.

I can't believe the vacuum pump would have picked this time to fail, but I guess it is possible. Any help would be much appreciated.
Thanks
