Well if it's not related I'll tackle that after Christmas ;-) ordered some glows anyway so I'll change them over....
Any news gone out this morning and hand primed, as I read warning the engine can make getting the injectors out easier! And I could hear a sucking noise and if I look it's the actual bleed screw undone the screw and all the threads are nearly gone in fact even with page tape it still sucks, I'm hoping that's it, I'm guessing or should I say praying that it wasn't a issue but after I repaired the pipe I've then damaged the bleed screw with all this priming.
