Honda GCV160 Lawn Mower Carburetor Diagram: A Complete Guide

If you own a lawn mower, then the carburetor is one of the most important parts that you need to take care of. The carburetor is responsible for mixing fuel and air before they enter the engine's combustion chamber, which makes it an essential part of your lawn mower's performance.

Overview of Honda GCV160 Lawn Mower Carburetor Diagram

Before we dive into more details about the Honda GCV160 lawn mower carburetor diagram, let’s first understand what a carburetor does.

A carburettor mixes air with fuel in correct proportion & sends this mix to engine cylinder for combustion & power generation . Gasoline engines use internal combustion process where small spark plug sets off ignition inside each cylinder as compressed gas explodes. This explosion creates pressure that pushes piston down , thereby creating power .

The amount of fuel delivered depends on how much air flows through choke circuit or throttle opening . This airflow determines how much suction occurs at nozzle tip located within venturi section (narrower area) – venturi effect generates vacuum which draws gasoline from float bowl into main nozzle .

Now coming back onto our topic i.e.,Honda GCVC 190 series engine has two different types/models in terms of their adjusting screws locations:

1- Vertical model
2- Side mounted model

Both models have similar working principle but adjusting screw location varies between them.
