Hello to the group!

I did not do one thing to the Mercedes this last week except drive! I have 793 miles to date and all is well.
It is a bit heavy on fuel so I will be working on the MPG issues. I have averaged 16 mpg hwy. I would like to know what the timing advance curve specifications are. Old school vets know what I am getting at, as I want to check to see if I have the proper advance at the proper rpm both mechanical and vacuum. Does any one know the specs?
Regards,
Bryan
