hey guys, I have noticed that the bottom auger will run dry for about 2 rotations, then will dump in a good amount of fuel but at that time the flame has gone down to the size of a cig lighter or is gone, thus causing some smoke because the new batch of fuel has to relight. my settings are 4-3-1, but have noticed it does this on all the LFF settings. the plate in the hop is wide open.....any other ideas?.....thanks
