have a o2 kaw 23 hp vert. that will run well for maybe an hour then will have to use the choke to keep it running for a short time. Carb. has been cleaned and checked by myself and 2 techs.Water drained, fuel filter changed, and tanks filled with premium fuel. Problem started with water and running rich then after the third try I got it back from shop running well for less than an hour at a time ( no gripe with shop) .

any thoughts
thanks to all
