Problem with air/fuel adjuster on 1989 Itasca Sunflyer.
Hi everyone, I posted my first question yesterday about a motor home I was thinking about purchasing (and DID purchase!), but now I am having difficulties with my moms motor home and need some advice.
She has a 1989 Itasca Sunflyer and is having some potentially dangerous problems with the hot water heater. She gets a ton of black soot coming out of the exhaust part and a strong odor that I can't describe and hasn't always been there. The flame is huge and orange. It's my understanding that the black soot means a likely blockage, insects, bees, something. Today I took apart the burner assemply and exhaust cover, verified that there were no blockages in the burner tubes, brushed the inside of the tube, cleaned the orifice with rubbing alcohol. I also blew into the hole where the flame goes in and an enormous amount of soot flew out of the exhaust side. I'm talking a good size black pile of soot on the ground! I connected everything, turned the hot water heater switch on and the flame is still huge, orange and has the black smoke (soot) coming from it. I adjusted the sleeve to give it more air and the flame did not respond at all. I slid the sleeve from side to side and the flame did absolutely nothing.
So what gives? All the research I come up with points to the air/fuel mixture, which I attempted to adjust and nothing. Is there something wrong with the sleeve? Something wrong with the orifice? The gas valve? I am out of ideas here, so any wisdom would be appreciated. Thanks!
