The Metz was not sold with an adjustable spark, and one is not really necessary. Be sure to set the spark a few degrees after TDC (top dead center). The timing is set with the gears from the crankshaft, so find the setting that gives you spark at TDC on the front plug (#1) and mark the flywheel. Then retard the timing by one tooth. You can check the timing with a battery-powered timing light against your mark on the flywheel.

Phil I know Metz but my Bosch has a movable collar to adjust timing advance/ retard

Not stock but what I have to work with haven't had the gears apart so they should be set

Still waiting my mag rebiuld  thank though for your input

Yes, Bosch made the DU4 in adjustable and non-adjustable timing models. The adjustable spark will work fine if you add a control cable or rod (and remember to retard the spark when starting!).
