I own a 1975 Evinrude 50hp Sizzler that won't idle. I have rebuilt both of the carbs. I have taken them off three times to make sure the floats are adjusted wright. I have also replaced the plugs. I also have unhooked the number two cylinder while it was running and seems not to change the rpm or the sounds of the motor. When I unhook the number one cylinder the motor will quite. Can You Please Help.
