I did have a look on ebay but only saw new TM36-68 carbs. Lots of stock carbs though.

 

Same thing happened to my (used) TM36-68. Not sure if I did it or previous owner, but it's part of why it has never stayed on my bike.

 

Good luck with yours.

FWIW I have a old CVK carb hanging on a nail in my workshop. It was off my old KLR 250. I dropped it one day while cleaning the carb, and snapped the boss that held the A/F screw clean off. Think that was $250 for a new one back in 1992.

 

Butterfingers!

 

Over on Advrider a guy in the KLX300 thread mentioned he's parting out and has a TM36-68.

 

Thanks for the heads up but unfortunately I've already bought a new carb.

 

Bummer, good luck with all that.
