I have a 92 cr 125 that wants to run away only with the choke off. the bike will start first kick with the choke on, after 30 seconds or so turning the choke off the bike acts as its WOT. Choke back on and it quickly goes back to a normal idle. It has power while riding with the choke on (more smoke than usual and felt a little rich obviously) but ran strong.
I used half a can of carb cleaner around the entire engine to check for a leak and there wasnt a single flutter in the idle (choke still on). After that I dropped the needle clip from the middle groove to the bottom. Harder to start with the choke on and wouldnt idle what so ever and smoked like a train. choke off instant run away, same as before.
Is there anything that I missed to check for? Is there another reason that can make it runaway beside being way too lean? ALSO I forgot to mention that I dont think this bike has the stock carb. It has a 38mm Keihin on it which i believe is the cr250 carb? PJ 38dgd111 is on the side of the bowl.

I would also check the intake for air leaks as well as the stator side crank seal for an air leak.

Also, I noticed that the coil isn't original. It doesn't span the gap between the mounts, its short about an inch. could this be a problem? I've searched the part number on it and can't find anything. Thanks for your help!
