I have reached the point with my rehab of my 250C where I would like to get the advance-retard vacuum setup looking somewhat original even if I discreetly disconnect it.

I have no diagram on this - it does not appear to be on the CD, and the parts book is of limited help. The setup that was on the car when I bought it is cobbled together.

I have the two electrically controlled valves on the right fender and the distributor with advance and retard fittings.

Could someone with a 114 250 or 250C with reasonably original vacuum plumbing describe the routing of the lines and the colors?

I have but one vacuum source, on the front carb. So I think it goes:

Carb to"Y"
"Y" to advance switch - front switch?
"Y" to retard switch - rear switch?
Advance switch to front fitting on distributor
Retard switch to rear fitting on distributor

Any help greatly appreciated. If it's easier, call me at my 800 number and walk me through it, and I'll write it up for the Forum.

Thanks

Chuck
