Took the petrol tap off of the RN as it had stopped shutting the fuel off. To get the tap off, needed to remove 3 of the 4 bulkhead tank retaining bolts.
Made a new set of corks for it from some 1/8" thick Walkers Jointing ((3 x 1/8" = 3/8"). Fitted it all back and as the fuel wetted the corks, they swelled up a little making the tap almost impossible to open or shut.
Drained it all down again, sanded the corks a little bit smaller and put it back again. Feels good now, no drips from the delivery side of the tap!
Incidentally, the thread on the tap "knobs" is 5/32 whitworth and the tap barrel is 0.360 diameter (which could be 23/64").
Whilst checking things over, I cleaned out the FZ22B carburettor (which was spotless since last visit 10 or more years ago) BUT noticed that both the Jet nuts and the jets themselves were almost finger tight - was that why there was a smell of petrol in the garage!!
