My 04 summit800 is mot starting and when if first died it sounded like it was running on one cylinder or running out of gas. So i pulked oof the carb and there was no fuel in the bottom of the csrb where the float is. So how can i test if the fuel pump is workung properly? And which line going to the carb is the fuel line? Any ideas on why there is no fuel going to my carbs?
