Motor will not idle below 1/2 throttle. Have cleaned carborator (all passages open), checked compression (95 PSI, even both cylinders), checked reed valves, checked ignition (starts easy) etc.<br />Will run at lower rpm's if we use the choke to richen the mixture, which suggests that the trouble is still in the carborator. But as noted above all passages in carborator are open.<br />t his is a tough one! I'm stumped! drmr1@juno.com
