back again with this dang motor,took boat out yesterday,would not start at all,been working on the timeing,now it starts good but runs wide open,what do i need to do to slow it down?i have moved timeing,up and down,i went by the book so set the timeing,just like it suggest,but it will not start,i have it now set at (timing mark set at :0:,arrow on the pully is pointing about 6 degress of the 0 mark on the fly wheel,to the right),if i move it any other way,it does not want to start,or it back fires.

You might tell us the year of the motor. They do have different specs for idle pickup timing and max timing.
