A spark ignited, gas fueled pilot assembly compromising a bracket and a metal gas tube extending through the bracket and having an outlet end. The gas tube is surrounded by a ceramic jacket which is of such a length as to extend beyond the outlet end of the gas tube by approximately 0.03″ such that the gas tube outlet is recessed into the ceramic jacket. The assembly further comprises a pair of ignitor electrodes carried by the bracket and arranged and located relative to the recessed gas supply tube to ignite fuel emanating therefrom.
