Your grate airbox under the grate is probably clogged.

See this thread and give it a shot!!

I checked the air box while putting in new feed motor. Since it was out I pulled off the grate and vacuumed it. There was not to much in there. Combustion motor seams to be working fine. It's lights fine but when it goes to idle it seams to go out.

It sure sounds like your not getting enough air. If the fines area was clear are the holes in the grate clear and clean? Are you by chance using a wiring scheme where when it goes to idle it slows down the combustion fan? How long after it goes to idle does it go out?

Check your "min" in setup, since both motors don't run exactly the same you need to increase it so they both stay lit. Usually 6 or 7 is enough, if you are lower than that it may be the culprit.

The min is set at 7. One burner is burning perfect and the other one is almost out. I don't get it.

Are the holes in the grate open for the air to come up through? I've had to stick a drill bit through mine to open them back up.

Are there any gaskets around the rear of the grate or grate housing that may not be sealing properly allowing combustion air to escape rather than coming up through the grate holes?

I seem to remember some discussion about a gasket on the LL's at the back of the grates, but may be remembering that wrong. I did a search but didn't come up with what I thought I had read. Any LL owners out there that can confirm or deny this?

Also check the " Fins " on the sguiral cage blowers, sometimes they fill up with dirt and need cleaned out to get more air movement.

Make sure the grates are sealed good (seated proplerly down, it can leak air out from under it and not go up thru the holes and the holes cleaned, the blower blades are clean, the blowers and stokers are hooked to the correct plugs/outlets on teh coaltroal.

Sometimes bumping the min up a point or two, like 8-10, it will keep the idle a bit higher.

check the stoker motor pusher bearing and make sure it doesn't come loose, mine did once, something got jammed in the pusher plate.
