Waste Oil Heater Forum - Your definitive source for burning waste oil for heat.

I have purchased a ckburner setup. everything is running, but i have a post shutoff nozzle drip that will continue to burn after shutoff. Sometimes a big flame sometimes a small flame. I have raised the front end of my float tank to allow for block drainage to no avail. Nozzle has no clog. Am running it at 5-6 psi. Am stomped as dont know what else to do, and its getting pretty cold quickly up here. any advice please!!
