The engine was originally designed and produced by Zanzottera Technologies of Italy, but the design was sold, along with the rest of the company's two-stroke ultralight aircraft engine line to Compact Radial Engines of Surrey, British Columbia, Canada.
Development
The MZ 34 and 35 both have a cylinder barrel that is Nikasil-coated. The engine features a decompression channel to allow easier recoil starting, a tuned exhaust system and a belt-type reduction drive. Starting options include a recoil or electric starter.
Earlier versions produced 26 hp (19 kW) at 6250 rpm or 38 hp (28 kW) with a tuned exhaust at 6450 rpm. The current production engine is rated at 27.5 hp (21 kW) at 6250 rpm. Reduction ratios available are 1.84, 2.05, 2.14, 2.24 and 2.34 to 1.
