Welcome to the board!:cowboy:

 

there are two vent lines that are on either side of the carb, just run them some where up high like under your tank cover. The other is your fuel line hook up.

 

There are three hoses that come off a valve near the top of the radiator, there four hookups on the carb, and im unsure of what goes where.

 

 

OK one the second pic(carb). #1 and #2 are simply vent lines. Just run them as high as possible.
#3 is the main fuel inlet for the carb.
#4 Is a vacuum port that operates the fuel pump(picture 1).
I will need to look at mine to see the proper routing off the fuel pump.

 

ok I got it. On the fuel pump. #1 is running to the fuel tank.#2 runs to the carb main fuel inlet(#3 on carb pic). #3 runs to the carb vacuum port(#4 on carb pic)

And carb #1 and 2 are vents.

 

Great You're the best! I'll give that a try, and let you know how it goes. I know this ATV have been sitting a year or two, and i've never seen it run, so lets hope for the best!!!! *Fingers Crossed*

 

Its low on oil, i'm going to do an oil change, and go ahead and put a spark plug in, its close to being fouled. What kind of oil should i put in? A regular 10w30 or???

 

5-50 or 0-40 or something around there is what I use

I need help! I had to work on the carb and now that it's back on it's not pulling fuel from the tank. Does the fuel pump need priming?

I just rebuilt mine, I had to put the charger on and try starting it in for about 2 hours, 10 or so attempts every few minutes so I think it does, couldn't tell you how though. Make sure your vacuum hose has a good seal/no cracks so it pulls a good vacuum on the pump.

Did you confirm that the jets on the new carb match the 425? There was a guy selling brand new carbs on ebay that need the jets swapped out. You should check your jet numbers before you install the carb. Even with the wrong jets, you can usually get the engine to start because the idle jets are all real close in size. Anything of of idle will start to show problems.

The fuel pump needs vacuum to work. Getting the hoses crossed would mimic a fuel pump failure so you"ll need to confirm. If the above info doesn't solve your issue, post back and I'll chime in and get you sorted.

I posted a few attachments and info on the 425 carb a year or so ago that you may be able to find if you search my user name. One was an animated file you can find on youtube that explains the function of your carb.

 

Burnz86, did that do the trick as far as the fuel lines? I have the same problem, but other blogs are saying the opposite, that 4 is the fuel inlet and 3 is the pulse line?

 

The pic is incorrect - 4 is fuel and 3 is vacuum

 

Ok on the bottom of the carb there is a small black hose. Where does that go? 98 425 magnum

 

Down between the engine and transmission to carry spillage from the carb away from the engine an let it drip harmlessly below the vehicle
