Volvo-Penta Diesel MD5A/110S - Cold Start/Stop Control

... just putting a boat (Grampian Discovery 7.9) I bought last fall in the water. Had trouble getting the diesel going but its running now.

Question is, looking at the back of the engine (from the saildrive side) what mechanism is the 'Cold Start' and which is the 'Stop Control' - bottom left versus upper right? The actual pull switches on the instrument panel aren't labelled and may not be standard/same as yours (hence my reference to the actual mechanisms on the engine itself). I have the manuals but they don't really tell/show you - they just say when to use them.

Thanks in advance

The cold start lever operates a rod which comes out of the top right hand side of the cover to the left and slightly above the water pump.
The stop lever is to the left of this. I've found I dont need the cold start unless it's winter time.Just open the throttle fully [in neutral of course] and start.Hope this helps.

I looked in all the manuals and can find no description of what the cold start system does. Does it allow the pump to pump more fuel ? does it change the timing of the injection ? My engine has an automatic cold start , I have learned that the cold start system is "set" when the fuel is shut off . I need to determine what it is supposed to be doing and whether or not my engine is doing it , but can find no description or diagrams or explanations of how it is supposed to work. Since my problems are limited to cold starts , I am sure that this is an area I need to fully understand.
