belldane Posted February 5, 2009 Report Share Posted February 5, 2009 Hi all. I am in the process of restoring one of the earliest Ty's and need an original second hand carb for it. The motor runs with the carb currently on it (not the right one) but is not running properly. No get up and go, bad acceleration and very very bad performance on full throtle. Any ideas where I can get one? or if someone has one they want to part with, please let me know how much. Thanks Quote Link to comment Share on other sites More sharing options...
tony283 Posted February 5, 2009 Report Share Posted February 5, 2009 The Ty250A came fitted with a TK carb, which was good for its time and if you can find a good second hand one will work well enough if you want to use the original posilube system. If you no longer have the oil system fitted remember to blank off the inlet at the base of the cyclinder. I would use a new Mikuni VM26 with 150 main and 35 Pilot, and maybe change, or clean the old reeds. There will be a TK for sale on e-bay soon! The TK was only fitted to the TY250A and was replaced in all subsequent years by a Mikuni and now with our latter day knowledge the VM 26 is the best and most reliable carb for this mark of machine. Go NEW and use 40:1 premix and for the 50 quid the money will be well spent and the performance spot on! I've rebuild about 30 TY250A's and never had a single problem with these carbs in reliability or woof! Mick Andrews enjoyed riding one of mine, and even signed the bike after winning with it.

dave dix Posted February 5, 2009 Report Share Posted February 5, 2009 Try this one but the mikuni's are better http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...em=190283307069 Dave Quote Link to comment Share on other sites More sharing options...
belldane Posted February 6, 2009 Author Report Share Posted February 6, 2009 Tony/Dave Thanks for the advice. I missed out on the carb you suggested on Ebay but will keep my eye out for the one Tony suggested. Thanks again. Manuel Quote Link to comment Share on other sites More sharing options...

Just don't get it on any of the rubber parts. Remove them first, and disassemble down to the parts you want to clean. Quote Link to comment Share on other sites More sharing options...
belldane Posted February 19, 2009 Author Report Share Posted February 19, 2009 Thanks DGShannon You would not believe what I found on the net. A carb specialist suggested that you put the carb into a pot and boil it in water for 10-15 minutes. Clears all the gunk out and just blow all passages. I did that today and the carb is fine. Just one problem though, See my posting on TY250 problem!!!! This is driving me mad!!! Quote Link to comment Share on other sites More sharing options...
