My burner used to whistle when it was burning it no longer does that. Any one have any clue why this is I dont think the flame looks as good as it used to. It is a clean burn 86ah.

Air 12-14 psi ?
What color is the flame ? Should be bright yellow with orange tips.

I have tried more pressure or less pressure and just cant seem to get it right I have played with oil pressure and air band. I cant seem to get rid of the sparkles in the tips.

Sparkles could be a variety of things. Water/anti-freeze will usually throw out big sparkles. Smaller ones could be lean from to much compressed air/combustion air or not enough oil. Also make sure both heating elements are working good.

heaters are both working just replaced the 50 watt one and have checked the other one the preheat block is around 140 if I check with a temp gun.I am thinking about removing the heater block and cleaning it off the gun with an ultra sonic cleaner I am not sure how big a job it is.

took burner apart today ultrasonic cleaned block and tested heaters cleaned the retention head readjusted the electrodes. I have a nice flame now running 3 pounds oil pressure and 15 pounds of shop air burn air band just cracked open a little.

when my burner was throwing sparkles i cleaned everything and/or replaced some things in the burner. my problem was the metering pump screen and filter were almost plugged. cleaning them solved my problem.
