Traxxas Engine Multi-Shaft Recoil Start

This is Traxxas's TRX 2.5cc Engine with Pull-Start.
This variation of the engine is equipped with two different length crankshafts.
60% More Power that the TRX Pro .15 engine!
** This engine is a .15 engine. The 2.5 refers to a measurement of Cubic **
Centimeter displacement compared to Cubic Inch displacement (.15).
Loaded with advanced features such and the totally free streaming rear exhaust, the
distinct composite slide carbohydrate, and ingenious porting only discovered on the most
exotic racing engines.

FEATURES:
Slide carburetor provides less limiting, directly through airflow
    for more power and much better throttle response.
Exhaust Header includes an extra-tough, finned installing base that
    dissipates heat and is sealed with a trustworthy O-ring gasket.
Molded head protector prevents damage to the head and protects the
    glow plug wire.
Innovative cast cylinder head is engineered for the most heat
    reduction possible.
Tubular header features smooth, rounded bends to remove exhaust
    flow restriction and turbulence.
Ultra-low restriction air filter provides remarkable air flow and
    filtration for more power and a long engine life.
Offset wrist pin further minimizes piston slide filling for more
    even cylinder wear, and longer engine life.
