For some reason my starter solenoid isnt giving the required 12 volts to open the elc choke the entire way. the choke is brand new with the carb. Where can i hook it up so that the choke will open all the way? instructions don't give a place, all they say is don't do it on the coil. friends told me not to hook it up on the batterty either. that leaves the alternator. if its the alternator, which of the three wires do i hook it up to?can someone help?
