Updraught Zenith FZ /FZB jets.

[Ray White]

I don't recall the values, but I have always found the same combination on FZ and FZB

Thanks Mike.  I repaired the FZB  many years ago but that repair has failed (not for the first time) so given that I have other carbs to choose from - including an FZ with very much less wear - I shall make the change.  I don't like anything that strays from the original where 'Trundles' is concerned but I think the time has come so what I am doing is taking all the best bits off of the poor old Mazak carb and fitting them to the bronze one.  

It cleans up nicely as well!

Ray.
