    RE: Issues with Mercruiser 5.0 LX 4 Barrel Carb

    its not advisable to leave the manual release open , although a lot of us seasoned boaters have at some time and operated the trim . in theory and from practice ( :) the odd time or 2 i have left the screw open and ran the trim) , air should not get into the system from there , so i doubt that...

    Starting issue

    + 1 disconnect the linkage , this will determine if it is carb (or TB related) or a sticking / broken cable , a broken cable can double up in the sheathing and cause the throttle to stick WOT . whatever you do get to the bottom of why its stuck WOT before trying the motor again.

    i did see that post , yes i agree it is "showing as" running slightly lean, retarded timing can appear to show lean or rich symptoms on plugs and valve heads. OP posted that after running for a bit it picks up , this is because the cylinder temp are probably getting to a point of being...
