I've found that for cleaning out the flame orifices in the burner tube that this Craftsman 40801 Feeler Gauge and Spark Plug Gap tool works great. Here is a link to one offered on ebay, but it's a little rusted out. I use the 0.30 Feeler gauge wire with the 90 degree bend. http://buy.ebay.co.th/buying/e...-Spark-Plug-Gap-Tool
