This engine comes with a Ceramic rear bearing and all new Crankshaft. More power, better fuel economy, and smoother power band. Best used with the 41021 manifold and 51018 (2084) pipe.

 Recommendation: This engine has been developed to be used with a fuel with a maximum of 25% nitro content and with an oil percentage not lower than 10% with 6% being Castor oil. We therefore suggest not using with different percentages compared to the ones specified here above.

Glowplug: The glowplug of engine is a Turbo type glowplug. The C6TGC is a good plug for all around weather conditions, 50’s or below use C5TGC.

Sleeve: The sleeve has 4 transfer ports, the best compromise to make a linear power supply with minimal fuel consumption combination possible.

Crankshaft: As this engine comes as "Factory Tuned" we have modified the crankshaft to further improve the power output and drivability.

Rear Ball Bearing: Inside the Ceramic Rear Ball Bearing you find High Quality Ceramic balls which has been proven to last long even under the most demanding races.

Rear cover: The rear cover presents a round shape; this minimizes the dead space and allows easy access for quick check-up.

Carburetor: The carburetor of this engine is made from plastic and in "reverse" style and has a sliding throttle valve.

Base Carburetor Settings: One turn out from flush on the top and bottom. For breaking in the engines turn out ¼ turn from base settings top and bottom and add a few drops of 1M1 NOVAROSSI oil in the glow plug hole and carburetor hole, rotate engine with flywheel 4 or 5 times before first start up. This will prevent a dry start up condition inside the engine.  Warm the engine with heat gun before first start up to loosen engine tolerances.

Suggested manifolds & tuned pipes: For this engine there are several tuned pipes available:
Manifolds: 41029, 41030, 41005, 41020, 41021.
Tuned pipes: EFRA 9901(51016) or EFRA 2084(51018). For more bottom end use EFRA 9953 (51017).
