Several issues ON WIFES 2006 REBEL
pipes very blue top 6"
could the valves have been improperly set at setup time? One cylinder seems to be missing some. Have switched coils etc
i finally have it running half-way decent, but i have to have the choke 1/2 way on.
IS THIS A CHOKE OR CALLED SOMETHING ELSE?
IS IT ON AT TOP, BY THE FLAP MARK OR IS IT ON AT THE PLAIN END OF THE MARK.
I HAVE NOT REMOVED CARB FOR CLEANING, BUT HAVE USED BUSTER AND COMPRESSED AIR TO BLOW ALL THE ORIFICES WHICH SEEMS TO HAVE RESOLVED THE ISSUE OF GUMBED UP CARB.
THANKS BOB (BOB2506)

The only way to know if your valves need to be adjusted, is to remove the valve cover and check them with a feeler gauge. Do a search on this site for "valve adjustment", and if you don't have one, I would strongly recommend a repair manual before you start.
As for the carb, if you have to use the choke to make it run after it's started, then your carb is not clean. You're gonna have to remove it from the bike and completely disassemble for a thorough soaking 24 to 48 hours in a good carb cleaning chemical following directions on the can, and then use compressed air to blow out all small orifices.

Hey guys and gals! I am new to this site. I am looking for advice on a fuel leak from the carburetor on a 2002, 250cc.

I am trying to determine the source of the leak before I take it off and repair it. According to the diagram above it looks like it is leaking from item # 47. The clip can easily be spun from side to side but not in a complete circle as it contacts the carb body. What does it do anyways? Is leakage from here common? Any suggestions on repairs?

As soon as I figure out how to attach pictures I will

Welcome. #47 is part of the throttle linkage, and has no direct connection to fuel. Did you possibly mean part #37? Check again and see if you can narrow down where the leak is coming from.

Keepin' all the left over parts. Gonna use 'em to build another bike!

Thanks for the welcome.

It is definitely not leaking from the drain hose. I pulled both the top and bottom hoses off to see if anything was flowing out of them and nothing. The whole body of the carb will get wet with fuel even above the float bowl. Although I admit this may be from wind while driving.

If someone could point me in the right direction for posting pictures I could point out to where I think it's leaking.

Okay...so I looked through the pictures on the second sticky post and noticed in one of the pictures something labeled a pilot screw. This looks like what I think is leaking. It's not labeled that in the diagram above but it may be item # 18.

Thoughts?

The pilot screw, also called the air/fuel screw, is number 22 above. Number 18 in the above diagram is the idle adjustment screw, which has ho connection to fuel. If the O-ring on the pilot screw has failed, that could cause a leak, as could a faulty bowl gasket, which isn't shown in the diagram above, but is part number 25 here: 2009 Honda CMX250C A CARBURETOR | Cheap Cycle Parts

To post pictures, in the Reply box, look in the tool bar at the top and click on the square with the mountains in it.
