New here but have been burning waste oil for a few seasons now with a sypon nozzel set up like ck burners sells, but i have just recentley started having trouble with carbon buiding up on the nozzel and electrodes. I had the oil temp set at 185f and lowered it to 160f thats when it really started carboning so i have since changed the temp to 185f. Just was looking for any ideas from people out there to see if this could be my probem or looking for ideas to try and help me fix my problems? Thanks in advanced for all your help/ideas
