I have a 1986 Mercury 115 inline 6, It is hard to crank when it is cold. I have searched and read where they are hard to crank when cold. But I noticed today when pumping the fuel bulb, fuel shot out the right side of the carb on the float bowl, it only does it on the top carb. It looks like a little screw in piece. That does not seem normal to me. Is it? The motor will start and run with a little help of pushing in the key till it gets warm.

Thanks

No, It is not supposed to do that. It is likely the top carb float is stuck or teh inlet needle is worn out or misadjusted.

had the same problem with my 1982 115hp and as said above it was a stuck float

Time for a carb rebuild then I assume?

I pulled the top 2 screws over on the float bowl and float works fine. I filled the bowl up with fuel.

It will only shoot out fuel after bulb gets hard and you squeeze it a few more times.

so I guess now i need to look into the inlet needle? how do i tell if it is adjust properly?

sometimes a few gentle taps to the float bowl can free a stuck float

I took the top of the float bowl off, yesterday, and cleaned what i could, then out it back together. It will still do, but only after i really squeze the primer pretty hard. Any chance i am just squezing to hard on forcing fuel out? the motor will crank and run fine. Is the any damage that can be done by running it the way that it is?.

Thanks

As long as teh carb doesn't leak while its running, you are OK.

Extra fuel will not damage the motor anyway.

Ok I carried the boat out today. It started up fine and would idle fine, when i tired to give it a little throtte it would die and not want to rev up and go. It did one time for about 2 mins then died back again.

Ideas?

the guy at the dock, told me I hate some dirt in the bottom of my carbs that was causing it. Sounds reasonable to me. So I guess i am going to clean and rebuild the carbs.

Also I looked on the little plate on my transom and got this off for a serial number: A154884 is that the right number?

Thanks

I wonder who is funding the cost for the parts on this motor?

[Chris1956]

I would think that you do have a carb problem. It could be as simple as a misadjusted idle mixture screw or dirty carbs. If you suspect the carbs are dirty, go ahead and clean them. Do a link and synch afterward to assure the timing is on target.
