83 300SD starter removal tips?

Hi:

My starter motor spins and will not engage 4 out of 5 tries, so I need at least a new solenoid.

It looks difficult to get the solenoid out, what with the heat shield blocking the wiring, and because I can't seem to break the (3) screws loose.

I figure the starter has to come out to replace the solenoid. I may replace the entire unit.

It looks like the exhaust head pipe has to move, because the starter looks too big to slip out any other way. Moving the head pipe will also make access to the two starter bolts easier.

84 300SD lock cylinder removal

The key had been sticking when I first tried to turn it over. One morning while in a rush to get the kids to school I put a wrench to the key to make it turn. My problem went from not starting, to not turning off when I turn the key off. The key now turns VERY freely and the steering wheel doesn't lock. I am trying to replace the whole lock cylinder but it doesn't want to leave its home. The cover sleeve won't even budge. The marks on the sleeve(0,I,II) have never lined up with the notch on the cylinder. Is there an alternate route to removing the lock cylinder? Or does anyone know how to get me out of this jam? It is very disheartening to pull into a parking lot proudly driving my old MB, only to pop the hood and press to e-stop to turn the engine off.

84 300sd Throttle Linkage Adjustment

Does anyone have any tips on how to adjust the throttle linkages on a 300sd? I messed up the tie rod that sets the idle the last time I removed the VC to adjust the valves, I want to bring it back down. While I'm at it, I'm hoping to find out what all the other linkages on the valve cover do and see if I can give the car a little "tune up". The tranny hasn't been shifting quite right after I messed up the idle too.

84 300SD Vacuum Question

Hi, I recently noticed that my transmission was having one of those downshifting noise when coming to a stop. I Checked this great site and found out that it was a vacuum leak issue. I checked the engine for any thing unusual and I found the vacuum line connected to the green "port?" was indeed disconnected. Connected it back and the tranny had the downshifting issue for while but goes away eventually. Drove the car today and I noticed that the downshifting "clunk" only happens when the engine is cold but shifts fine after the engine is warm.
