Hi JetBlack82---------If this is an '82 ZX we're talking about, there is no choke. The function of the choke is taken over by the cold start valve on the EFI system. If you're getting an unusual noise it may be the starter, particularly if it seems to drag or turn over slower than it should. Any big parts store can usually check a starter out for correct operation. One good indication the starter's failing is that it tends to get very hot when you crank the engine over.
