Trigger Replacement on 88 Merc 150

When replacing the trigger should any lubricant or grease be used to aid in its function, if so what type is best, dielectric or other.

all I found in my manual was to coat connections with liquid neoprene but not sure how necessary it is

A quick question on link and sync procedure. I only have a Seloc manual, which is vague at best. When setting the idle stop screw, it says align the edge of the throttle cam with the front edge of the throttle stop screw boss. How should it be aligned or any certain spacing. The pic shows a 1/8 in. gap and that is where i set it, is that correct. And when setting the max timing, I could only get a little over 19 deg., it should be twenty. But, I guess it shouldn't hurt any.

One trick on the trigger is that the harness from it needs to be on top of everything else that is going across or to the top of the engine, free to move, and held in place by only one ty-wrap on the side of the switchbox mounting plate. If it binds, it can limit the travel of the trigger for timing.

I haven't had trouble getting 19 or 20 degrees, but when discarding the advance module, sometimes you have to open up the slot in the stator mount to clear the harness for the last couple of degrees of travel.

hope it helps

Yes, that does help, I willl check that tomorrow after work, but I am pretty sure that the harness is free to move. I did pull the advance module. I just installed a new stator and trigger, and will check for trigger movemet and if it is hitting the stator mount. On the idle stop screw, the procedure is unclear, how critical is this. Doesn't sound like much to me, but still would like to know.......... Thank you

John, You were right on the money, one of my stator bolts was stopping the trigger from moving its full travel. Put a few washers underneath it and was able to get to 23 deg. Thanks for the great advice.

Most of us wrench heads have been there. Glad it helped.
