Fuel Delivery Problem? Carb Problem?

4 posts in this topic

I have a 1987 60 hp Mariner that is being troublesome.

I don't know much about motors but it seems like I have a fuel delivery problem to the carburater. For example...

The first problem is that it can be very hard to get it to fire for the first time of a trip. Often times it finally fires after I disconnect the fuel line at what I believe is the fuel filter under the hood and let the fuel drain out, then reconnect it and for some reason it will often times then fire.

Secondly when starting during the trip it can be hard to get it to fire, lots of pumping the bulb and starting before it fires. Then even after I let it high idle for up to minutes when I go to put it into gear it dies.

Once it is in gear and running no problems. Yet when I bring it back out of gear after driving for a while it can die then as well.

I am wondering if I have a carburater problem that either needs a cleaning or a rebuild or something? Or if maybe it is as simple as adjusting the idle speed However, not sure if that will solve my initial problem of getting it to fire when the engine is cold. Any ideas on what I should do? Thanks for any help you guys can give me.

I guess the first thing I'd try with it would be to re adjust everything from the idle mixture to the timing and sychronizing, new plugs, check for leaks, check the primer bulb and that kind of stuff. However it may just be time for the carbs to be rebuilt.

Have you checked the compression ?

I've pretty much checked over all the fuel lines, bulb, spark plugs etc. I have not checked the compression. I don't own a compression tester so I think I may be leaning to just bring it in and having someone with actual knowledge look it over. I sure hope the motor isn't shot.

    • You might be able to figure things out this week.  How big is your sump basket?  Is the  pump kicking in now?  Sit there for 15 minutes and count the number of times it cycles.  That should give you a decent idea on how much water is coming in.  Then figure out about how high the water has to go before it flows by gravity.  The spec for the pump will say something like that it can pump 2,000 gph at 10 feet of lift.  (the gph drops dramatically the higher it has to pump the water).  The answer to your specifics will give you an idea of how big of a pump you need.  If you match the size of the pump as close as possible to the amount of water your will face you can maximize the amount of time the battery backup will last.   Faced with this problem I took a standard boat sump pump and modified it so I could hook up a garden hose.  The I took an old shop extension cord and wired the pump so I could hook it up to a car in the garage.  So just prior to having Noah float by I could hook things up in the garage and be good to go for as long as I had gas in the car to pump up the battery.   Now that I am adult I bought a generator and wired the house to take care of things.
    • Inevitably at least twice each season I will leave the house, drive 45 minutes and walk some of my favorite grouse spots for hours and hours, seeing nothing.  Admitting defeat on that day, I will drive 45 minutes back home, only to find a covey of birds in the driveway...
