Having said that I haven't encountered this sort of problem doesn't mean that sticking needle won't happen overtime after the mower is sitting iddle for a while. I haven't heard from customers or warranty return since. The needle has already shown an issue (sticky) when placed manually outside the assembly that's why I develop the spring clip to prevent this foreseeable fault condition from happening and also to fix the current issue. I wish Norm you fitted with the spring clip you made before modifying the carby and install a drain tap to check if fuel is filling up the chamber and needle is closing the valve.
