Help! Force 120 problems

[123456]

I have a 98 Bayliner with the 120 Force outboard on it. I wish I had went with any other brand than Bayliner and Force. I have had problems since day one with this boat. I am having a problem with my engine now. The warranty is expired so I don't want to take it to the dealer unless I hae to. The problem is that both of my carbs shoot fuel out of the sides of them. I had just finished replacing the gaskets on the carb bowls(?). I hooked fuel line back up and pumped it a few times. No more leaks from the gaskets, but now fuel shoots out the sides of both carbs. It comes out of a hole on the side. It looks like some kind of little port or something. Is there a hose that is supposed to connect the two carbs. I don;t think there is because I don't remeber seeing a hose there before. Sorry for the long post, please help if you can.<br />Chris <br /><br />------------------<br />1998 BAYLINER CAPRI 1800<br />120 HP MERCURY FORCE

Re: Help! Force 120 problems

There is only one thing that can cause this problem.<br />A stuck float valve needle inside the carb.<br /><br />Gently tap the side of the bowls,while someone pumps the ball. It should quit.<br />It could re-stick again at the worst possable moment,so I would re-build the carbs before venturing out.<br /><br />Remove it.<br />Take the bowl off.<br />Remove the pin holding the float to the carb body (like a tiny door hinge-pin).<br />Try not to bend the stop or otherwise change the adjustment of the float.This is easier said than done, but be gentle.

<br />The needle valve is in the body of the carb,and is probably stuck in there. But get some tweezers,and pull it out.<br />Get a can of spray Carb cleaner,and spray it thru the hole the needle came-out of,till your sure its clean. This model may have a rubber seat in the hole,so let the cleaner evaporate good. Also,clean the needle valve with liberal amounts of the spray. DO NOT soak the needle or carb body in a carbonic cleaner (that comes in the gallon can).These cleaners will desolve all plastic and rubber.<br />The spray cleaners are the same,except they contain a drying agent,so it evaporates within a few minutes.<br />Re-assemble your carbs, and they should be fine.<br /><br /><br />------------------<br />Time to change my tagline
