1978 450 SEL High Idle 2000 RPM

I have just acquired a 1978 450 SEL and based on the records the motor has about 35k miles on it since a complete rebuild. It starts up and runs fine (wants to die if you give it gas when cold) once warm. It drives great but the idle is high at about 2000 RPM cold and 1700-1800 warm. Not sure where to start.

Vacuum? Is there an idle control of some sort that could be bad?

I don't see an idle adjustment and don't know these gas engines so I'm lost.

Thanks for any help!

15" Wheels for a 85' 300SD

I am now the second owner of a beautifully maintained 1985 300SD. However, I would like to change out the 14" Bundt Alloys with a 15" Mercedes wheel. I prefer the 8 slot chrome wheels I see on 190s and w201s. The problem is this, I cannot find a straight answer on the Benz forums if there are any stock 15" Mercedes that will "bolt" on correctly in relation to offset size.

Any insight would be appreciated.

1985 300SD Cable Broke - How Open Hood?

When the body shop repaired my 300SD, they nor I knew about the hood cable adjustment. It was FULL TIGHT and just snapped the other day. I got hold of the cable by reaching into the slot above the driver side headlight...the cable is disconnected from the release "latch" on that side. I can easily pull it and release the passenger side latch, but that does NOTHING for the driver side hood latch. How can I get to the hood latch on the driver's side? What do I have to do to release it? The front end is pretty much all new, but not everything is a real factory fit.
