Ok I have reached my boiling point lol. Here it is I have a 1986 mercruiser 3.0 carberator, points timing system. We bought the boat last spring and I had a heck of a time starting it. here is what I have done so far I have replaced the dist cap, rotor, coil, points, condensor, spark plugs, fuel filter. What I finally did was advanced the timing to get it started. it starts great but you can tell it is out of time but funny thing doesn't seem to bad no back firing just loss of power. Than when I go and set the timing to 6 degrees bdc it won't start. So I thought I would just set the timing the best I could and take it out and, I had to advance it alot to start. It ran ok but you could tell that the timing was off but not too bad. Shut it off after riding around for awhile than it wouldn't start back up. Came home replaced the battery the next day and she started right back up but still not in time, every time I would set the correct timing or even close it wouldn't start. I set the timing way advanced again starts great but again runs sluggish. Took the boat out again this time ran it for a couple of hours pulling a tube with kids and the timing seemed to get worse so tried adjusting it on the water, well it died and couldn't get it started again. Went back out this morning she started right up on the first try set the timing and now won't start . I did this morning adust the idle a little bit as well as the fuel air mixture on the bottom of the carb. I am so confused as to why it will start when the timing is advanced so much any ideas would greatly appreciated have a family reunion this week would like to take it out but don't want to have to leave the boat running all day long. it will stay running but as soon as you shut it off get the paddles out cause your not going anywhere.
