What are you using for fuel? My Saito’s like Powermaster YS/Saito 20/20 fuel. Your idle will probably settle down after 3or 4 more tanks of fuel. Then you should be able to lean out the idle as described in the instructions. </font></p><p style="MARGIN: 0in 0in 0pt" class="MsoNormal">Saito motors are shipped with a rich idle mixture for brake in. </p><p style="MARGIN: 0in 0in 0pt" class="MsoNormal">Is the motor inverted? </p>
