Ladies and gentlemen,

For your amusement... the saga goes on...

and after some VERY helpful suggestions I FIXED IT!

Now, getting the car ready for competition this weekend and... hey, 
what's that smell?  Surely it is just residue from the previous fuel 
leakage?  Nope - maybe it was all the fiddling with that little hose at 
the float bowl end but guess what - yep, now I had leakage from the 
carby/jet end!!!  No competition for me as it was too late to repair in 
time on the morning of the event and scrutineers HATE fuel leakages 
(and rightfully so).

So now I return to Barney's earlier mail where he was talking about the 
"wrong" end of the fitting - now it is the RIGHT  end.

OK, I picked up the whole fitting (hose and jet) from my mechanic and 
will replace it entirely - luckily now I have had practice refitting 
the floatbowl end of the hose... maybe this was all just meant to be 
"good practice".
