Thanks Guys, and yes i purchased the M4MC service manual as I have the WB blue 308. Perhaps i can just state that i highly recommend the Rochester publication, as i am very impressed with the technical detail in the manual.

I purchased mine from this link- http://www.carbkitsource.com/carbs/t...jet-index.html and it was a good purchase for $6.95

Anyone needing to rebuild, tinker or learn about their carby will get heaps out of these.

Cheers
