hello, i bought a ty250 that had its Needle Valve assembly destroyed by bad gas, i have searched high and low for the part and cannot find it. I would buy a new carb for it but i dont have $200+ to spend on a new carb for that year. So i was wondering will a 76/81 dt175 carb work on it? or any other cheaper carb?

The float valves are same in most Mikuni carbs ,, I swapped a N,O,S ts Suzuki valve into the DTcarb,, both carbs were Mikuni v28"s..

no idea what version this TK carb is, from what i'v gathered it was unique to the 74/75 ty250.

what about the link i posted?

From the look of it it's going to sit too high. I may be mistaken as the needle i had was corroded pretty bad, but the nut itself doesn't look like it would sport a very long needle.
