Check the gas/ air-------------------
Check the gas/air mixture tube for any obstruction (bugs, spiders). It may be necessary to blow the tube to clean it out with compressed air to clear any obstruction. I even had to remove to clear it of a large dead spider. If there is an obstruction in the tube, it will cause an uneven flame.
