Your best bet would be to look at ebay. I had a look but could not find one now tho. Or contact Jack's Rebel Warehouse. Or maby jax can help you (he has helped me out a couple of times. And Is a grate guy).
If you get the complete intake manifold and carb you should be able to use any rebel carburetor.

Sorry to evoke the old thread all of a sudden, I am also in the same boat. I have a Honda CM250 and it seems like it needs a new carburetor to run properly. CM250 LA Custom. I am thinking of looking for a brand new carburetor and Chinese made GS125 Carburetor seems fit in with jetting changed it might work. I might try it out, if it works i will post it.

Carburetors rarely needs replaced, 90% of the time they just need a thorough cleaning. Sometimes they need new seals and float valve. Once in a great while they will need new diaphragms. Hardly ever does the whole carb need replaced unless the carb body has been damaged or broken.

the cm 250's carb is cake to go through... just pay attention... go pick up a gallon of carb dip... pull it COMPLETELY apart and dip the body and all of the hard parts (no rubber, etc.. just metal parts) overnight... then clean them with a good carb cleaner and blow it out with compressed air.

reassemble and set the idle mixture screw ~2.5 turns out to start with.. let it run for a bit (which while ur at it... pull the tank and clean it out... flush it out really well with water... then with rubbing alcohol or gas... if its rusted inside, seal it)

Anyways... it took me ~30 minutes or so to pull apart the carb and reassemble... not including the time in the dip can.

Ive got a few pics of doing it too... so if you get stuck... just ask. $30 in a good cleaning beats paying for a used carb of unknown condition or paying full price for a new chinese knockoff.

Good luck!

it would not be so bad if it was a rubber diaphragm carb. mine is a aluminum diaphragm and bust be wore out. had it checked over 2 times by a pro shop and still no luck. we stuck a carb off a durt bike and ran fine. So we are on the lookout for an aftermarket carb that will fit and connect.

I just did mine this spring. It's a very easy carb to clean. Just get the schematic diagram from here:

https://images.cmsnl.com/img/partsl...ornia-carburetor-83_bighu0165e4c1501_4b12.gif

or get a Haynes manual with the schematic. Take the bowl off the carburetor and take the primer pump apart. Take out the jets and soak them overnight in carb cleaner (or kerosene) then blow them clean with compressed air. You can find a few vids on the Keihin carb on YouTube. Yours is very similar to the Keihin on the Harley Davidsons 1984-1999. It is a very simple carb that is a dream to work with and tune. They get clogged because people don't drain the bowls on them.

Hey Chris, any chance I could get you to post some pictures of the throttle side of the carb all hooked up? I need to reattach mine and I want to make sure I'm winding the springs properly and then putting the cables back in the right place. I forgot to grab some pics of mine before I took it off and disassembled it Thanks -Corry (fellow 82' cm250c owner)

I appreciate it. I may have to do that. I responded on here because previous poster said he had pictures I could definitely use.
