I have a boat with the above mentioned motor that has a 4-barrel carburetor and I am needing some help in getting this going.

I got it to start and run for about a minute but it would not idle and seemed like it was missing and now it will not start. When I pulled the motor out of the boat two years ago to rebuild the whole interior of the boat it ran like a champ.

I just replaced the fuel pump, spark plugs, oil, oil filter and fuel filter, along with cleaning the tips in the rotor cap and the battery leads. The carburetor is getting fuel but I'm not sure if it's flooding out the engine or what the problem is to be honest.

I am needing some help with this problem.

May be a distributor issue if it went from "missing" to a no start.

How old is the gas? Did you try starter fluid?

One time my choke valve wasn't closing and I would press it down by hand to get it to start.

The gas filter is new and so is the gas. When it first started I used staring fluid and it did crank but would not idle and seemed like it was missing.

The fuel filter is new and the gas is new. I did use starting fluid when it cranked the first time, and I used it again the 2nd and 3rd time. So that's part of why I was thinking the engine was flooded.

Did you clean the carb? Sounds like it could be a clogged jet

I would put a kit in the carb and clean everything really well. Sitting for extended periods of time is not good for carburetors.
