Paul H Posted April 25, 2017 Report Share Posted April 25, 2017 Hi just upgraded all R6 fuel pipes to R9 grade - I was very careful about cutting the rubber pipe and used a pipe cutter with a stanley blade. My vitesse fired up ok though it was clear one carb was leaking from the float bowl gasket . Stripped the carb and found the culprit , a sliver of rubber stuck in the needle valve Hope this helps someone else Paul Link to comment Share on other sites More sharing options...
Ben Caswell Posted April 25, 2017 Report Share Posted April 25, 2017 Possibly from pushing the rubber connecting pipe onto one of the metal connections!! Took me weeks to find the little blighter as in my case it was actually stopping the fuel flow through the needle valve, but only when on full demand IE trying to overtake or going up hill..

Pete Lewis Posted April 25, 2017 Report Share Posted April 25, 2017 Youve been stung with one of my avid hates , the blighters are everywhere Every hose connection disturbed is a potential for these floating slivers, Its a good case for reducing the number of hose /bundy connections and use decent rubber in longer lengths and delete some bundy One idea/ solution is to add a flare to the pipe so no sharp cutting ends , helps seal and the hose clip cant slip off. Same as coolant pipes pete Link to comment Share on other sites More sharing options...
AidanT Posted April 26, 2017 Report Share Posted April 26, 2017 I purchased a small pipe cutter off eBay which does exactly as Pete says. I've not had a problem with these slivers when I replaced my rubber pipes with R9 Aidan Link to comment Share on other sites More sharing options...
