Default 1978XL 125 carb adjustment.

Bike has set for 20 years. How do I adjust the carb on my 78 XL 125? Bike is now running but rough and won't idle. I'm 75 and still riding. It's a blast.
Thanks in advance.

Other than an idle-mixture screw and throttle-stop, there's not much "adjustment" on most carbs. Have you disassembled the carb and cleaned all the tiny orifices (jets and bleeds) thoroughly with spray carb-cleaner and/or compressed air (and sometimes a bit of fine, soft copper wire)? If not, I think you can figure-out why it won't idle.
