Mercedes Benz repair: 81 380SL Hard restart, number search results, mercedes benz 380sl

Question
I have a "81 380SL Runs well -I have adjusted the Idle mixture- no surge at idle.
The problem I am having is.
After the initial start-up-(starts right up& idles
no problem when cold)
It is hard to start-it does start just takes a while and then it idles rough until i goose it a few times and then settles in and idles well.
And runs well there after-Timing is correct & have cleaned the thottle body.
Ideas?
Thanks,
Pete

Answer
Best guess:

#1. Ignition Coil old age failing, note: wrong coil can blow your modules.
#2. Check Valve and/or Fuel Accumulator
#3. Ignition Control Unit, the weather seal fails on these = corrosion inside = strange ignition/starting issues, especially when warmed up.
