Hi,

I have a 87 force 50 hp outboard and I am having a problem that I can't seem to fix. It starts right up and sounds like it running normal but when just in test tank and revved high quickly in neutral it will not return to a normal idle after you let off it has a high idle and will stay like that for 2-5 seconds it seems like it is running lean because if I cover the throttle body with my hand it with drop down. I took the carb off and blew carb cleaner and air through all the passages and they were all clear. there is only a idle adjustment and idle mixture screw to be adjusted on it. I set the idle mixture screw to the factory location and that didnt seem to help it any. I'm guessing the carbs need to be rebuilt on this one I bought a rebuild kit but didnt use it cause the carb seemd very clean...

Cliff notes:
87 force 50 hp
after neutral revving it 1/2 throttle and above, it high idles for a couple seconds then will return to a normal idle after a couple seconds
idk how to fix it
