Re: 96 mariner 115 makeing popping noise
If you are reving the motor at the carbs you are not advancing the trigger...If you are reving from the throttle arm then that isn't it...Is your base timing correct? You say you are running 100 to one..I would hope you are referring to the oil injection where at idle it is 100:1 and full throttle it becomes 50:1....your motor won't last long if you are premixing at that ratio....I am with Jake in regards to lean conditon... You need to make sure the idle mixture screws are adjusted correctly..at least 1 1/2 turn out for being turned all the way in gently. Only the bottom two carbs will be adjustable....just trying to grab straws here.....
