Thanks Jeremy. FPR seems to be the same part as for the M20. I will see what my "test" tomorrow brings and, if I still have the problem, I would like to try your spare.

Like you I have already replaced a few bits. My first thought was the HP pump as that was also making a strange noise. They ain't cheep and it didn't solve the problem Grrr. I can see now why some people still prefer carbs!

Cheers, Robin
