I have a lanair mx200 that I cannot get to light. It done this to me the other day and I drained about 5 gallon from the bottom and it worked fine for a couple days. Tried to drain it today and it still won't light. The only thing that comes out when I drain it looks like oil. Could the water not be settling out? I'm about fed up with this thing temped to sell it. It's been more trouble than its worth.
