hey.. so im relatively new to boats and carbeurated motors so i figured i would ask this perhaps stupid question.

i have a 2000 chaparral 205sse with the 4.3thunderbolt card motor and i am doing basically a complete overhaul on the boat and i had purchased the k&n flame arrestor for $100 bucks from autozone and was just going to pop it on but i am now thinking that i will most likely have to adjust the carb to allow for the additional air flow from the new flame arrestor. how would i go about doing this?

I doubt it will change the airflow from a marine flame arrestor.
