For years I have used 'gas taps' on the racers and road bikes
They don't look original but they have always worked well compared to the corky ones of my earlier days especially with the unidentifiable petrol we have in the UK today. However I have just put two new ones on the Egli Comet I am building, and having been caught many times before with initial petrol leaks, I carry out a 'leak down' test for a day before starting the plot. Next day leakage was evident which I tracked to the taps and on reducing the system to just the taps after a few minutes one was dry but the other had a drip, a small but annoying one,and a further day of exposure to the supposedly ethanol laced petrol (who knows?) has not reduced the leakage. Are they completely non-adjustable? have I just got a Friday one? what is your experience?
