I have the line on the very top with the p going to the right side of the carb. The bottom back line towards the front of the quad is going to the gas tank. The back bottom one towards the rear with the filter is going to the left side of the carb. Is this right?
And by the needle are you talking about the large needle in the middle of the carb or the float plunger with the rubber tip? Is the big needle in the middle have a rubber seat or something its supposed to sit in?
Sounds like the lines are right. I'm talking about the float needle in the bowl. That is what controls the flow of fuel into the carb and stops it wen full so it doesn't overflow and flood the engine out. Sometimes they wear out, sometimes it's just a piece of crap that gets in there and keeps it from plugging the inlet hole, I've also seen plenty of floats that no longer float or are set incorrectly by the rebuilder or by accident when putting the bowl back on.
You set them level with the carb body when upside down. With a new needle and seat is will definitely be off. Bend the little tab in the middle that touches the needle, not the float arms. And a little goes a long way.
Little update. Rebuilt the carb and it STILL floods the motor! Float is adjusted perfectly. Only thing I noticed is where the choke threads into the carb, the other side is just open and looks like a pice is broke off from the outside. I think theres supposed the be a pipe or something on the outside but its broke off but that still wouldnt cause it to flood like it does.
It can certainly leak past the o-ring if it doesn't seal well. Find a way to pressurize the fuel inlet to 5-7lbs of air pressure with the carb upside down on the bench with the bowl off. It should hold that indefinitely. If not you can usually hear and see where it is leaking from. I use a mighty-vac product that will do positive pressure or vacuum pressure.
Oring around the seat where it presses into the carb body. It's late and going off memory here so I might be thinking of something else. Part 37. Guessed at a year of machine since you haven't posted it.
You mean if you take the bowl off and turn it right side up the float will fall out. Leave it upside down so the needle is closed into the seat and stops the fuel flow. Like it would if the bowl was on and it was installed and full of fuel.
