i have toomeys and 280 mains, i recently had a problem with my carb, do u think the mains are too small or what ?

What exactly is it doing? is it bogging down? Or is it heating up rapidly? Does it seem to sputter? Is it reving high but your getting no power? You're kinda vague with your explaination of what is going wrong.
