I just found a 2008 TW in Florida with 16 miles on it. Despite the varnish smelling fuel, it runs ok but will not idle after turning off the choke.

I have spent a bit of time reading all the carb related posts (lots of them) and have been unable to find information addressing this sole issue.



Using common sense, I drained the fuel and cleaned the tank, removed the carb, cleaned out the bowl, needle and jets. Filled the tank and added a couple of ounces of Techron for good measure. All appeared great.



Started fine, warms up and I close the choke and it quits. As if I hadn't touched it.



I see a lot here about altitude. I brought the bike home to Tennessee from Miami. I understand I am nearly a thousand feet higher now but there is no difference with this issue. Personally, I have never had a problem with a carb equipped bike being "out-of-tune" from less than a thousand feet of altitude change. Even with some very high performance equipment.



So, I am turning to the experts.....You guys. My first thought is to raise (shim) the needle a bit but I will just be throwing darts and you guys should have already thrown them.



If anyone has some advise I would appreciate you sharing. Otherwise, I guess it's a trip to the dealer.

Did you remove the pilot/mixture screw and clean it and its respective carb orifice thoroughly? That's part of your idle circuit. If clogged, that would explain why its running only with choke. Take a look here (identified on bottom view of carb) for what part I'm talking about... http://tw200forum.com/index.php?/topic/937-tk-carb-photos-and-parts-identification/page__pid__19750#entry19750



The 1000 feet is not your issue. Don't be rejetting until this issue is fixed. A 2008 with 16 miles still probably had the same gas in it from when it left the showroom.

The same exact thing happened to me 2 weeks ago with one I bought. My carb was dirty and I needed a new float. It starts right on up now.

Symptoms indicate a clog pilot circuit. If it was mine I'd do a thorough carb cleaning. The passages in these carbs are tiny.

Ok thanks. I will try again paying close attention to the pilot/mixture screw and passages.



Will post the results.



Thanks again!!

did you get it running duke? considering buying one with same issue.
Vidwiz, this thread is 5 years old, but the "choke only" problem is common.

A cleaning of the pilot jet/circuit in the carb is usually all that is necessary.
