Most probable....fuel pump. First i would make sure the pulse tube (from the engine case to the fuel pump)is secured tight. If you are getting pulse from engine and no fuel to carb.....bad pump

Also, pull the carbs and clean them.

Water in the carb bowls. Remove the big nut on the bottom of the carbs and drain them.

ok well thanks for the directions guys ive had a problem with the carbs icing up before so im gonna check that out for sure but the carbs were just cleaned about 2 weeks ago

only running on the primer means it's starving for fuel.
if your sure the carbs are clean and not iced up (it's real warm out now), then the fuel pump sounds like the problem. check any fuel shut off valves to see they're open too.
