A completely new carburettor has been build-in for an even better adjustability especially when in at idle speed. The performance, especially when stationary, has been improved with this move. All in all, the ZR.28 Spec.4 offers more torque with better adjustability and improved responsiveness.
Otherwise being a giant, it is a true midget in its dimensions. Due to its compact construction the engine can be used as a direct replacement to the .21 engines. The ZR.28 Spec.4 fits into all common .21 engine mounts.
