Any diagrams of timing screws or advance/retard module(mercury xr4/150hp)

[xxturbowesxx]

I'm trying to remove the timing/retard module and set the timing on my xr4. the pictures in my seloc manual are useless. Also I am trying to identify the timing advance/retard module and cant find a good picture of that as well. Thanks in advance

From the picture the oil injection features and spark module has already been removed. Where is front air box? If it does not have one check the high speed jet size as this will cause engine to run lean @ WOT. By the way nice 1 piece cowl !!
(1) max spark advance screw
(2) primary pick up timing screw
(3) idle stop screw
(4) max throttle sop screw
