After replacing rebuilt carburetors the engine won't turn over...

[Capt Al]

Just rebuilt two carburetors on my twin 4.3's. I reinstalled them and started the first engine up fine but the other engine won't turn over. Engine starting wasn't the issue before. I can see gas going to the carburetor. A mechanic took a look at it and noticed that the nut on the coil is spinning and won't tighten completely. He's bringing another coil tomorrow to see if that's it. Does that sound right? Any ideas?

process of elimination....you see gas....how bout a spark??...is the cut out switch at the helm accidently turned off....check all electrical connections...

Won't turn over at all, or turns and won't start? Fuel, spark, air... Since the carb takes care of 66% of the equation and that is what was removed, I'd start there as well. SP has a good point as well, it never hurts to put the boat into gear, then back into neutral, as well as check the emergency shut off.

Seapuppy,
You win the diagnostic guessing contest. It was the "kill switch" at the helm. The switch is broken, probably condensation during the winter layup. I ran a wire bypassing the switch and it started and ran well. Even though the other switch is OK, I'm going to replace it as well. Thanks for the advice....
