1991 Mercruiser 4.3L V6 Timing Setting?

[mmadlener]

Hello All!!<br />Please be advised; I am not anywhere near a mechanic, but I am not afraid to get my hands dirty. Also, I believe in life there are no stupid questions; just stupid people (I proudly display "Stupid" and chance I can get).<br />OK, with that little disclaimer out of the way, I can ask my stupid question. <br /><br />What is the correct timing for a 1991 Mercruiser 4.3L V6 2bbl? <br /><br />I am having problems restarting the engine after it warms. If I let it sit for more than 10-15 minutes after running, she is very difficult to restart. <br />Basically, she has been out 1 time after a winterization. She runs much worse than she did before winterization. I have only had the thing a season and before I put her away for a long winters nap, she ran great. Heck, I could brush myself against the ignition last season and the boat would fire!! I am thinking it could be as simple as "Bad Gas," but I don’t want to leave any stone unturned. <br />I just completed a tune-up (everything other than timing) and I am going to run some "HEET" and new gas through her this weekend. <br /><br />Thanks a bunch and I hope you all can help me bring my baby back to the way she was!!<br /><br />Sincerely, <br />“Rapidly Loosing my Hair in Seattle”

8* BTDC..............<br /><br />I Think you've got a Fuel Issue..............<br />With Any Luck....<br />It's the Gas.........<br />If Not, Look to the Carb.............

I have to agree with Bondo. An engine does not get out of time just sitting there, but fuel does degrade.

Bondo, <br />Yes, it was Fuel and it is the Carb!<br />It makes total sense; she fires right up after sitting for long periods (overnight). Even if I turn the Key right after I shut her off, she fires! But when I wait for more than a minute, my defective "Pin and Seat" allow tons of Fuel to fill the bath, thus flooding the engine!!!<br /><br />After the successful removal of our old friend the "Sasser" worm, I am now searching for a New Carb!<br /><br />Thanks a bunch Bondo and I am sure I will be talking to you in the very near future!!<br /><br />MadSearay!
