I installed the Yugo Distributor I got from Jeff S. in my 128sl, it works great. Does anyone have specifications for the Bosch control unit and the distributor advance curve? The control unit # ends with 123.
I notice as I was setting timing that there seems to be a slight retard of timing just off idle, and the dwell time is variable according to rpm's, from 33 degrees at idle up to 55 degrees at 3000 rpm.
I didn't attach anything to the vacuum port on the dist. as I have the 32 DATRA which is set up for a vacuum retard Ducellier. I set idle timing at 12 degrees BTDC, but didn't spend much time checking full advance as the engine ran great and it was only about 15F in my garage. I'm wondering how much mechanical advance there is if I don't modify my carb for the correct vacuum porting.
