Re: 74' 135 hp johnson PwrShift II Carbs?
Eric,I don't feel anything normally at fault in your carbs will make them run rich.The float level could,but you'd see gas leaking around the carbs.<br /><br />You say the carb chokes are 100%.Open then closed.Unless someone added parts from another year,your choke should have three wires.Two purple,one black which is a ground lead.The two purple ... One activates the choke fully,from the switch at the remote control.The other applies partial choke until the temp sender on the cylinder head shuts it off.<br /><br />Just the way it was then,but anyone could have changed anything.<br /><br /> When the motor is warmed up and running,see if the choke plates ARE wide open. (sounds like you have done this,maybe not) if the choke plates are closed partially when warm,the temp sender on the cylinder head is bad,or you have a wiring problem.<br /><br />Another thought,a bad fuel pump diaphram could be pumping fuel into the cylinders rather than thru the intake.<br /><br />Of corse,you motor is 32 years old,and the oldies wasted a lot of fuel,by design.<br /><br />DHP
