Motor - 1967 Model 350, 35 hp Twin, ser number 2258858.<br /><br />This motor requires the choke to start. It does not matter if you you have run it for two hours or 2 seconds. It will not start unless the choke is fully closed. After the first attempt you can go to half choke. Then you can slowly return it to fully open and it will run. You must keep the idle up or it will sputter and die.<br /><br />I have noticed that when I spray seafoam throug the carb, the idle smoothes and it seems to run a lot better.<br /><br />Everything looks good on this motor. It has strong compression (more than I care to pull repeatidly). The spark is strong. And the Carb looked pretty clean when I had the filter off (did not take it all the way apart).<br /><br />I have an electric choke on the way, but currently I am using the manual knob and my toes to turn the key.<br /><br />While I have your attention. Is this a coil, points, ... setup. With the age of the motor. I thought that might be a problem, but all the wires are flexible and still have their coatings. Is there anything under the flywheel I need to clean or adjust.
