Available as an option on GCV and GSV models

Honda’s Auto Choke System is available for use on GCV160 and GCV190 engines in fixed-throttle lawnmower applications. This user-friendly system is truly automatic, eliminating levers and cables.

The engine starts easily whether cold or hot and is ready to use immediately.

Once the engine is up and running, the Auto Choke automatically returns to an optimal operating position.

All engines

Honda’s automatic mechanical decompression system is designed to give you quicker, easier starts.

This system, which is connected to the camshaft, reduces compression by opening the exhaust valve slightly when the engine is being started. This reduces the amount of force needed to start the engine and improves starting performance.

The system disengages automatically after the engine starts to prevent any power loss during normal operation.

Mini 4-Stroke Series

In addition to the milder operating noise of 4-Stroke engines in general, the Mini 4-Stroke’s belt-driven OHC design further reduces unpleasant mechanical noise. Its lighter piston and other moving parts help keep vibration to a comfortable level.

GC series, GS series

A truly innovative combination of a compact combustion chamber, overhead cam configuration and uniblock construction significantly reduces fuel and oil consumption as compared to conventional side-valve engines.

Honda’s simple design has made the GC and GS Series lighter and more compact than any engine in their class.Auto Choke System Plus, simple construction has minimized the number of parts, making the engine more reliable and easier to operate.

iGX Series

The electronic governor minimizes governor droop. This increases available power.

For most normal engines, available power is decreased when the engine is approaching wide open throttle.

The iGX’s advanced electronic governor eliminates this by electronically controlling the throttle to achieve a higher effective power output.

Mini 4-Stroke Series

The innovative design of Honda’s Mini 4-Stroke engines allows them to be used and stored in any position for full 360° usability. Upright, sideways, even upside down – the Mini 4-Strokes will still run great.
