Dell orto PHBH26FS carburettor , This carb I believe is used on various trials bikes , I do not know what it originally came from , The carb needle is marked X 36 and the two jets I can read are #170 and #48
Good complete condition apart from missing choke and these can be easily sourced , I have turned all the jets , air screw , idle screw so nothing broken or seized
Please be sure from the photo and information given that this is the part you require
Any questions welcome
