A 750 is just lovely for a mostly street 482. Just replace the needle and seat and you're likely to be good to go. If for some reason you're not, then you'll have to pull the bowl off and look for either a stuck or leaking float. You could probably get away with just blasting the existing N/S with compressed air, as it's likely just dried gas, a zinc flake, or the like. BUT.... a stuck N/S is a potential engine fire issue, as the gas can come out through the shaft, on to the hot pipes, and that can lead to a very bad day. So, just replace it with a new one. Pay particular attention to the little "H" number that is stamped on the side of the existing N/S so that you get the exact same. I know the rebuild kits come with about four of them, and only two will fit in, but one is incorrect and will still fit. |
