I have a 98 force 120hp and I want to clean the carburetor . Somebody can tell me what to do or if I need to buy a kit or something?

I'm not an expert on these but there are kits available for Force carbs. I would say find the type/serial number and buy the rebuild kit. Then pull it, wash it, and rebuild it. Most of the work will be in cleaning it really well, check the manual for all the holes, tubes, pins, floats, etc, that need to be cleaned.

Good Luck

Thank you. But what can I buy to clean it?

Re: 1998 force 120hp carburetor question

get the carb rebuild kit that Mercury sells, not one from an aftermarket maker.

Mercury part number 809807A1


part # FK10023 for the gaskets



Soak and clean parts in carb cleaner, available at any auto parts store.

Do not mix the parts from the 2 carbs.

The first question is: Why do you want to clean it? What problem are you hoping to correct?

While cleaning a carb is a relatively simple task, it is also a fast way to get into trouble.

As I have said before: Carbs are like women's breasts--- they stick out in front of the engine and the first thing men want to do is mess with them. And, if you don't know what you are doing, you are going to get into trouble!

That said, If you still need to clean the carbs, I like to use WD 40 and pipe cleaners. That will clean most varnish and the rest can be removed with just a little scrubbing. WD is easier on the skin and less aggressive than carb cleaner. You can also use the red tube to power spry out some goo in passages.

Thank you for all your help. The problem that I have is when I get the boat in the water I spend a lot of time to start the motor and a lot of smoke. Also if I stop in a place for a wile
And try to start the motor it takes a lot of time to start it again. That is why I want to do something

Well, before you go messing with the carbs, remove all four plugs and either clean or replace them. Force engines are notorious for fouling plugs and hard starting is the symptom.

If that does not help, then check the enrichment system. This is a solenoid off one of the manifolds and a couple of small black rubber tubes that run from the bowl of one carb to the flanges of both carbs. this takes the place of the choke.

Correct starting sequence is to put the control handle in fast idle position and press in on ther key while turning to start. The smoke may or may not be indicative of a problem--these engines do smoke a bit, especially on start-up.

O! M! G! 50 billion hits! My 15 minutes of fame.

But I don't play with them--I know what I am doing--and still get into trouble.

Re: 1998 force 120hp carburetor question

Yes frank playing with them is an art from . And there are so many variations. The positon of the jets varies more than you would at first think. Freeing them so the work is easy can be confusing with the differing positon of fastenings ....Sometimes a re spray is in order .Oil can be quite usefull. All the ones I have seen have twin carbs but multiple jets are quite rare.
