yes they all have the cap on them and are black. but they are 8 ports. and let me tell ya you either get a good one or a bad one- and i got a freakin bad one- it wouldnt keep running for crap. they say its the carb but, you mine as well buy a new motor for the price of a carb. and i have 5 motors and they all run great! this was the ONLY one i hated![:-]
