Merc carburetor

[clutch442]

A buddy has an 1980 model Merc 40 horse. When you squeeze the primer bulb fuel run out of the carburetor. I am assuming its something with the float and the carb probably needs a rebuild. Anybody ever mess with these? Are they a pain to rebuild? Its an odd looking carb, I don't mess with Mercs much. Any leads on best place to get kit/float for it? Any help appreciated.

It is a very simple carb. The floats are bad about getting holes in them and filling up with fuel and not "floating". Parts are readily available most anywhere that sell mercury parts.

It look like this?

That is it James thanks! Up until this it was running well. May just throw a new float in her and see what happens.

Just pull the 2 screws off (#12 and #13) and pull the float out and look at it. If it has fuel in it, it will be easy to tell. May also be a piece of trash in the needle and seat. You will have it in your hand when you look at the float. Pull it apart and and clean it.
