if it sat a long time, i would drin fuel tank,( might even have to flush it out), remove carbs, disect and clean thoroughly, new pump or rebuild it. Should be good.

clean carbs and fuel pump,shou;d be able to do this without getting any parts,sound like carbs are gummed up.dont mix carbs from side to side or changing jets from side to side

the pump is workin like it should i cleaned carbs when i got the sled and gas is good. I had to dis onnect the ignition cuz i broje the key when i was unloading sled so idk if that would make it run like it does

Pull valves out, clean, replace seals and gaskets.

My 2000 summit 700 was cutting out on me intermittently and more so over half throttle and always starting up after first pull. Since the sled had been sitting for three years I assumed it was the fuel. I drained the tank (premium) and filled it half full with a good shot of sea foam and ran it for 15 km with the same issues. I the cleaned the contacts on the DESS also squeezing the key together where the contacts go up the sides. Same issue. Not until I changed the plugs did it run strong. The plugs looked good but apparently the ignition is fairly sensitive.

That leaking on the left side most likely the bellows has a crack in it.
