This is just a guess, I have an 87 40hp. But it should be close to the carb. And will likley have a small lever on the side of it should be red or orange. Should have two wires going to it.<br /><br />Good luck!
my 87 25 hp johnson doesn't have a choke, it just has a primer. You pull the primer nob out two times and it acts sort of like a choke. maybe your motor has that set-up instead. how many nobs are on the front of you motor? <br /><br />Heres a pic of the primer assembly in my motor<br /><br />
