Also.....I've seen, I *guess* you would call it plastic dust in the fuel tanks of these Chinese bikes, looks like the dust from when the petcock hole was cut.
There was also reports of incorrectly machined carb/intake manifolds, where the "O" ring sits, and ultimately doesn't seal up the intake tract. A "tight" intake valve may be the problem. |

if all above fail, check the float needle. it sounds like it might be starving for gas and the float needle needs to be "open" up some more. let us know of what you find.

took the carb apart and cleaned it out drained the tank for plastics, bike still will stall when it is taken off choke, you can keep it running if you short crank the throttle but it is gasping when you give it throttle, there is no restrictions in the fuel line. will the carb off a 110 rebel fit the 140 dirt bike, my sons is working fine and if it fits it would be a good way to eliminate the carb

The other carb will likely fit fine, but it probably won't feed the engine any better. Have you tried adjusting the air / fuel screw and the jet needle clip yet? The fact that it won't run without the choke tells me that it's starving for fuel.

cleaned all passages, and checked for obstructions, no slime or dirt in the bowl and float does not stick, haven't adjusted the needle yet but will set it up a couple of knotches, it seems to be as low as it will go right now

What does "as low as it goes" mean? The reason I ask is that some refer to the clip, while others refer to the depth of the needle.
To confirm: if you place the clip in the lowest groove, you will obtain the richest setting. That is accomplished because the needle will be lifted as high as possible upon opening the throttle, and the jet will be fully uncovered. In this way, we have dropped the clip and raised the needle. Apologies if you knew that already. If the clip is indeed in the lowest groove, I'd flip the carb over, remove the main jet and buy a larger one. Typically, they're only a few dollars at the local motorcycle shop. I find that my local Yamaha dealer sells the Mikuni style, while the Honda dealer carries the Keihin style. YMMV.

the clip is in the highest groove or lowest position for the needle, I am going to lift up the needle and see what happens

If the clip is in the highest groove, try placing it in the middle groove for now. If you move to the btoom groove right away, it might be a bit too rich.

Just remember that the pilot jet / A/f screw will control the idle mixture ( if your A/F screw is more than 2 turns out you should go up 1 size in pilot jet), the needle jet adjustment will take care of the midrange mixture and your main jet will control 3/4 to WOT.
