I put in the timing control knob b/c it would over run every time I would shut it down. Timing was set at 33, when I would try to lean out the idle airs it would run too hot. Now every time I shut it down I retard the timing. The knob is mounted under the steering column. 7 degrees +- When you got good fuel and cool temps... turn it up. I really like it, easy to hook up and only 129$
