Hello i have a 1978 Yamaha DT175 with no carb. i have the throttle cable, throttle valve, and the cap for the top of the carb. ive phoned around and looked for a direct replacement but i cannot find one anywhere. Does anyone know of ANY brand oem/aftermarket carb that would fit this specific bike? i realize this is difficult so im hoping someone who knows these bikes will be able to help me out. im not sure of the specs on the old carb and cant find them, so any info or a part number or website would be greatly appreciated. Thank you for your time.
