Changed from #1 to #2 fuel oil as is allowable according to the manual for a M-EG1 Wayne oil burner. The flame will not ignite. I put on a new pump, electrodes, and oil filter out at the oil tank. If I raise the transformer 1/4" or so it will light and then 30 seconds later the primary will kick out. I've adjusted the air intake rings, electrodes, and electrode bracket every possibile position that I can think of. I get the same result each time. Any ideas?
