Have a 78 140 ph Merc with a Rochester carb. Had some issues right after buying the boat and have done a tune up, including plugs, points, new filters, ect... Got the info from here on where to set everything and it is running now. Went to do the timing and found another problem (I think).
When I went to adjust the idle I found the bracket that holds the idle screw is loose a little. If I move it back the idle is right where is needs to be, but as soon as I throttle up and then back down it is staying at about 1100 rpms. All I have to do is move the bracket with my finger and it will go right back to about 650. I could not find any screws or bolts that hold this bracket to tighten is up. what am I missing???
Thanks,
Jeff
