May cause confusion for those not familiar with the carb set up. Poster #2 [07/17/10] Why are they not included? Does the fuel line from the gas tank plug in directly to the bottom port near the flow bowl of the GY6 Carburetor? And there is another port located at the center of the carburetor? Is that a fuel vent port that has a hose connected to it that just hangs down? Where does that port go? Poster #3 [08/24/10] Rating 1/5 where is the gas line Poster #4 [Travis @ BD-ORB] [02/20/11] Poster #3: The fuel line attaches to the brass barb on the driver's side of the vehicle (left side). You'll know it when you see it, as it is the only brass barb on the carburetor. Poster #2: The fuel line, overflow, and drain hoses are not a part of the vacuum system. We left these items out to make it easier for those looking to troubleshoot vacuum system problems. Poster #5 [03/01/11] Hello, I have problems with this carb as well, there is a brass barb on the carburetor that was not hooked to anything, it just sticks out, it is on the float bowl. Where is this supposed to connect to? Poster #6 [04/01/11] I have gas coming ooy of the carb overflow. I think,it id=s the shourt rubber hose not connected to anything and gas is overflowing out of it Poster #7 [04/20/11] On the red line drawing mine has a Y in it and neither end is connected any I deas. Poster #8 [04/23/11] poster 5 it is an overflow it usually just has a hose that hangs off to let any extra gas that got in to drip onto the ground but its not suppose to leak or you have a float problem Poster #9 [09/16/11] What should i do about my vacuum lines if i dont have an airbox... Poster #10 [09/24/11] get an air box (w/a filter) and connect the lines to it. you dont want ANY debris getting past the intake port into the cylinder and causing havic. its the easiest way to seize the engine. then you have to pay for more than just the air box. Poster #11 [10/17/11] does the air intake hook on to something. when i try to start it it will not start unless i hook it up to the thing going to the motor. when i start it it will start when the air intake is hooked onto som,ething but only go 15mph and it suppost to go 60mph. why is that i have a hammerhead 150cc go kart Poster #12 [11/05/11] I have a question.. there are 2 lines on the carb.. where do they go..can you give pics or illustrations please. I am including a link to a pic from bmi karts. I really need to know where the bottom hose (next to the screw) attaches to.
