I think there is only one thing to add,

You need to pump the primer pump through the adjustment. Not clearly called out in the proceedure, but I believe Ritter told me that a few years ago.
I don't think the piezo electric things work that well with benz's. Later cars have a place for using a electronic measuring tool. It's a dream on post 82 cars. THen again, once you set on up- it's good for years.
