"hi there this is my first pos

"hi there this is my first post, i have two problems with my 50hp yamaha twin,
1st i have just bought it and i dont know how old it is, on the plate it is a 50ce then below that it has 6p4 then the seriel number i have gone to the charts and there is no year for the c series i take it she is older than 1984 but how much i dont know
2nd she wont tick over without adding a little choke as we found out yesterday, when before this we would start her up useing full choke on the key start she would scream at high revs and then just cut out. I am taking this is down to mixture or worn jets and seats, if so then the delema starts i dont know the year and ordering parts will be dificult although i did notice a number on the inlet manifold and dont know if this would be relavent when ordering. I havent gone to the extreme yet of stipping the carbs as now she is ticking over on partial choke thinking it may just be mixture and also taking advise from you guys first.
hope you can help alasdair"
