KF Engines vary by manufacturer, manufacture date, and tuning. For optimum performance, you might need to try different settings. Below is a list of recommended settings, starting with the most recent/most popular first. For best results, start with the most recent and then adjust first the High, then the Low needle each in 1-minute increments up to 3-5 minutes each (extreme conditions like hot or rainy weather may require a little more). If you are not satisfied, repeat the procedure with the next setting.
