Carbs Leaking Fuel

[bh357]

1963 Merc 1000 Inline-6. The carbs appear to be spraying excess fuel from what I believe to be the main jets (angled tube in the throat). I really noticed it when I was cranking the motor, with the choke on. Also, a fair amount of fuel flowed out of these tubes when I tilted the motor back after running.<br />All carbs were cleaned and rebuilt, with new floats, and the needle valve levers set according to the manual. The bulb did get firm when I primed it. The motor idled fine after it was warmed up, and warm starting was nearly instantanious. She seemed to be difficult to start cold.<br />Thanks for your help.

u may have to re-adjust floats.

mellowyellow,<br />I'm guessing I should adjust them so they close sooner. Is that correct? Do you think that it would make cold starting easier?<br /><br />Thanks

Re: Carbs Leaking Fuel

have always used the "even w/top of carb when<br />up-side down" meathod my self. as 4 starting,<br />they like lots and lots of gas. primer her up<br />good and then add a couple extra pumps. what <br />worked well 4 me was to primer her as I was<br />prepping to launch, then again when she was in<br />the water. u can do a search here and read for<br />hrs. on this subject... they are notorious for <br />this.<br />good luck,<br />M.Y.

Re: Carbs Leaking Fuel

I started up the motor today, and it started up within 5 seconds when cold. Pumping the bulb until firm didn't flood the carbs, however one time I did get a little overzealous pumping the bulb, and had fuel leaking from the carb. Is it possible to apply enough pressure to the bulb to force the needles open? Or, do I have to reset the floats so they close earlier?<br /><br />Thanks.
