This is the LRP Nitro Engine ZR.32 Spec.4 Pullstart Nitro Engine. The LRP ZR.32 Spec.4 Pullstart is based upon the very popular ZR.32. In order to be able to again increase the enormous power of the .32 monster, we build in a completely constructed carburetor that has an additional notch for improved adjustability and that provides an even more efficient fuel-air mixture.

This leads besides an improved idle speed setting, also to better responsiveness and more torque. The already known Heavy-Duty CoolDown- Max cylinder head provides sufficient cooling for this power unit.
