    Is the float blocked. Is the spark plug wet. Are you sure it's getting fuel.

    Easy(dirty) way to check. Spray a lynx deodrant into the combustion chamber and try and start it. If it fires into life (even briefly) you know it's a fueling issue.

          @Oisin Well it's a fueling issue then by the sounds of it.

          Take the carb off and ensure the needle isn't shutting the float off.

              @Calum I checked the float and adjusted it to be in line with the carb bidy itself. I cleaned out the fuel tank and tried again, still nothing. Any ideas on what gat I can do next? Would it be worth talking of the side panel of the carb and looking in there?

                I'm sorry, I'm really confused.

                The bike was working, you then broke a fuel line and now it doesn't work?

                So quite clearly the only thing that's changed is that fuel line.

                  @Calum I know I'm lost myself what else could it possibly be like. So frustrating

                          @Oisin is it possible at all that when you replaced said fuel pipe it was connected back up incorrectly/ wrong place/wrong way around? Just a thought.

                            @Oisin maybe check said fuel pipe is actually allowing fuel to pass through. I presume it's a new pipe but stranger things have happened.

                              @markus-w I had this when I replaced it with a silicone host, it kinked and stopped fuel from flowing.

                              Use properly braided and rated fuel hose. Is my advice.

                                @Calum yes I agree. That's good advice. Some parts it doesn't matter so much but there's certain things you just can't skimp on.

                                      @markus-w It appeared to be kinked under the fuel tank and so I couldn't see it. I also have the tank a good clean out which helped a lot I think
