Help! I have a 51 Mercury and need help with the carb choke plate adjustment. So no matter what I cannot get the plate to open up all the way or the idle to drop After the flathead is warm and I press on the gas. I need to know what I’m doing wrong. Here’s what I was told. With the weather between 65-70° loosen the carb choke spring housing. Press the gas pedal in between 3/4-1/2 down and turn the choke until the plate opens then turn back in the opposite direction until the plate closes softly. Then tighten the choke spring housing and it’s set. Here’s the issue, doing this several times the choke plate never fully opens up when fully warmed up and the idle screw never drops onto the lower lobes dropping the idle. First question - What lobe should the idle screw be resting when the motor is cold? Right now it’s on this one. Second question - I live in California so would I still need to press in the gas pedal when making the adjustment? It seems that by doing that it would keep the carb choke plate closed longer and if the spring doesn’t unwind that much when hit it would stop the plate from opening up all the way. Third question - typically how many lobes will the idle screw move when it’s cold going to hot? Any help would be greatly appreciated. Thanks!
