I have had the same problem but this will probably fix your problem -> http://www.scribd.com/doc/27325375/Y...ce-Manual-1999
the carbs should be the same..
Iv just taken off, cleaned and rebuilt the carb on my 2002 tw125. Admittedly I didn't look at the service manual, and now before I went to put the carb back on I checked the manual I have... its for a tw200, and the carbs are different. The carb on mine is a TK carb, but a different model to the one's on the tw200's. The differences I can see are that it has a choke cable going up to the handlebars, and the throttle cable is connected by a twist cap on the top of the carb. the reason I'm putting this up is just to get any information on the carb, and to ask about the choke assembly that I think was the problem in the first place.
Thanks a lot guys,
thanks, thats a brilliant help. I stuck the carb back on an its fine just now, started up after a bit of work... and not a small amount of falling over....
