Jet Size

I have a 05 Foreman 500es 4x4. I have installed a triange atv snorkel, my exhaust is snorked, hmf eco exhaust, k&n air filter, and jet kit. Can someone please tell me what size jet should be on it. I have a 155 now. I live in s.florida. The problem i am having is when i get in water it stalls. If i pull the choke then it will start back up, however it takes a while for me to get full throttle. I have plugged the carb drain abd greased the spark plug. Can someone please help?

change out the 155 to a 170
i went down to a 150 jet and it runs great. thats a dyno jet 150 jet. a factory 170 jet is about the same as a dyno jet 154.
check you plug, see if its black. i bet you need to go down to a 150 dyno jet.
