    Carb ?

    I need a question answered from someone that knows alot about carb's and modifications. Well here it goes, a guy brought his snowmobile carbs to work today B/C his sled is running rich, he had the throat bored out. would that cause it to run richer or leaner with stock jets?

    THANX
