1980 450 SLC Engine Stalling after long run

Hi Folks ,
I recently bought a 450SLC in reasonable condition with a view to restoring.Motor starts fine & goes well.
I took it for a long run a couple of weeks a go & covered about 150kms without incident until I came back to town & stopped at traffic lights. The car started jerking when I took off & started loosing power. I managed to get home with problem slowly getting worse.
I turned the engine off & restarted it a few minutes later & it seemed to be revving cleanly again , but didn't take it out again until a couple of weeks later.

84 300d turbo Valve adjustment and compression test

Two quick questions. I am about to adjust the valves (5cyl 617) to do a compression test on an engine that has not been turned in a couple of years. I just took the valve cover off and everything looks as it should. No sign of corrosion anywhere, oil still present on surfaces.

Should I put oil down the cylinders prior to turning for valve adjustment?

How much in each cylinder?

Thanks

88 190d shut off lever staying down/ hard start

After I drive my 190D and shut It off,I noticed it has a hard time to restart sometimes.It has been like this for awhile now.After checking things out, I found that the stop lever on the injection pump stays down and takes a long time to come back up.Would this be a fault in the shut off valve?If i have someone hold the lever up the car starts right up.What would cause this to do that?
