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