Hi my name is Victor! I joined yesterday. I’ve been asking about a Foreman 400, but my posts keep getting deleted. Am I doing something wrong here? I’m just a new guy looking for some help.

What's your problem
Well, a friend brought me a 2002 Foreman 400 which he said wouldn’t run. I put a new battery in it and some SeaFoam in the fuel in the gas tank.

The bike turned over and after 3 tries it fired up and ran. But, there is fuel blowing into the sir box, via what looks possibly like a PCV line from the tranny? Just a guess. Any way, after 2-3 short running events it has put about 3/4” of dirty fuel in the bottom of the air box.

There is no filter in the box and no lid on the air box either. If you look at the attached photo, the fuel is blowing out, rather rapidly, via the small square in the bottom of the air box (see red arrow) .

I would appreciate any advise on how to prevent this flow of fuel into the air box.

had this problem with my 06 rubicon 500. the needle got stuck open and i had to rebuild the carb
OK. I’ll pull the carb and check the needle & slide.
Im just guessing here, but it would seem if the needle/slide was stuck, I wouldn’t be able to activate the throttle, which I can do. What do you think? - Victor

Yes. I had the same suspicion that there was fuel in the oil since the fuel coming in was blackened from dirty oil.
I will change the oil, clean the carb and see what happens. Still surprises me that the bike will run and rev up if this is the case. On a 2 stroke motor, if this kind of thing happens, it won’t even start! - Victor

What is holding the carb onto the intake manifold? Is it just a clamp, or is there something else I should know about.
Also, does the forum have a shop manual stored anywhere? I don’t have one to read/follow thru in. - Victor

One of my problems is I physically can not bend over to see where the screw head is….

It’s going to take some doing to get at it. Thx! - Victor
