Hi Steve, was wondering if any gas furnace burners have a #70 drill hole in a threaded piece with a filter on it. . I use a venturi burner for my propane forge that has a #70 drilled hole in a piece of pipe, once in a while a speck of dirt gets in the unfiltered hole and I fool around with a wire from a small brush to get the crud out of the hole, or blow it out with air.

Now that I'm thinking about it I might look into a oil burner/boiler nozzle which are filtered with sintered brass on the intake end. I have a oil fired boiler that we use for hot water heat in our house. have serviced it for 31 years, maybe i answered my own question.

Thanks,
