While checking the K jetronic CIS fuel injection system on my M110.988, I noticed that my warm up regulator has a screw sticking out of one side. It is the correct part for my engine Bosch 0 438 140 103 or MB 110-070-00-62 so it has not been swapped.

I understand that a WUR can be modified to allow adjustment, but I thought it was the other side that received a hole. Not sure if this screw is an adjustment, thought it held on the heating element.
Last highway tank, all highway mileage was 12.6 miles per gallon, running about 75-80 mph. Also pulled the fuel injectors to check for leaks or a bad spray pattern, they appear to be original. Anything else to do while I have the injection lines and the fuel distributor off the intake manifold to replace the boot?
