Emission Control System Information   

 

Source of Emissions   

 
The  combustion  process  produces  carbon  monoxide,  oxides  of  nitrogen,  and 
hydrocarbons. Control of hydrocarbons and oxides of nitrogen is very important because, 
under  certain  conditions,  they  react  to  form  photochemical  smog  when  subjected  to 
sunlight. Carbon monoxide does not react in the same way, but it is toxic.   
 
This utilizes lean carburetor settings and other systems to reduce the emissions of carbon 
monoxide, oxides of nitrogen and hydrocarbons.   
 
Tampering and Altering   
Tampering  with  or  altering  the  emission  control  system  may  increase  emissions  beyond 
the legal limit. Among those acts that constitute tampering are:   
 

  Removal or alteration of any part of the intake, fuel or exhaust systems.   

  Altering or defeating the governor linkage or speed-adjusting mechanism to cause the 

engine to operate outside its design parameters.   

 

Problems That May Affect Emissions   
 

If  you  are  aware  of  any  of  the  following  symptoms,  have  your  engine  inspected  and 
repaired by your servicing dealer.   
 

  Hard starting or stalling after starting.   

  Rough idle.   

  Misfiring or backfiring under load.   

  Afterburning (backfiring).   

  Black exhaust smoke or high fuel consumption.   

 

Replacement Parts   

 
The  emission  control  systems  on  your  engine  were  designed,  built.  We  recommend  the 
use  of  genuine  parts  whenever  you  have  maintenance  done.  These  original-design 
replacement parts are manufactured to the same standards as the original parts, so you 
can  be  confident  of  their  performance.  The use  of  replacement  parts  that  are  not  of  the 
original design and quality may impair the effectiveness of your emission control system.   
A  manufacturer  of  an  aftermarket  part  assumes  the  responsibility  that  the  part  will  not 
adversely  affect  emission  performance.  The  manufacturer  or  rebuilder  of  the  part  must 
certify that use of the part will not result in a failure of the engine to comply with emission 
regulations.
