Engine converted to run on 20:1 gasoline . <br />Prop 20x10 <br />Idle 650-800 <br />WOT 6400 <br />I will say a 22 x 8 or 10 may be better and bring the WOT RPM down to 5200-5500 will sound much better. <br /> <br />seen that the pressure tank was not necessary in later testings. <br />For more visit website: http://www.choklitmolds.com/
