I lost interest in the benz this past year. I purchased the Mac Tools pulse adapter in April and never got around to the timing... I posted my pulse adapter for sale but figured I'd try it first. The car runs good but I wanted to check.
From my previous quetions on timing I came up with 14*-15* BTDC
The car is a low mileage 81 240 D manual 4 speed. Valves were adjusted last year with hardly any miles on since. I have not checked chain stretch which I wil do this weekend.
My questions are
1. Is the round open metal plate circle hovering over the dampener the TDC mark? You can see the balancer pin in the opening. Yellow line indicates TDC.
2. I assume the timing marker hover over the balancer is the tab below the TDC marker. I labeled it C. in (red)
3. The white mark on the dampener is the 14* degree mark at about one o'clock on the dampener past 0* degree TDC. if facing it from the front.

so far so good?
A, is the timing light and set at 0*( A.) it reads rightthe white line right on the red on the red tab at 14*....
My questions is... when I dial it back to 14*degrees the white mark drops down into the 3 o'clock position if facing it from the front..
Shouldn't the white mark be on the timing tab when dialed back to 14*degrees?
Am I on the right track and good where it is or am I off by 12-14*?
When I timed my small block chevy I just dial it to 12.5* and turn the distibutor till she lines up on the timing marker at TDC. I assume the same applies here.
thanks for the Input.

The tab is your timing mark. Are you reading the TDC mark or the degree markings? The tab with a hole is for a tack pickup AFIK from 617s

From what I have read on this forum about the "Pulse" type tools that use a pressure transducer that clamps on the Fuel Injection Hard Line is that you need to time you IP with one of the other timing methods first. When you are sure the IP timing is correct you set up your Pulse type timer and record the degrees you get and use those degrees as your standard.
From then on you can use the Pulse tool to check your timing and use the degrees you recorded as your standard.
