Gum content
Gum content is one type of gasoline performance.
When gasoline evaporates completely, it leaves a yellow or brown
gum or resin substance.
If a type of gasoline with a high gum content is used, it may
cause the sticking of the throttle valve, clogging of the
carburetor nozzle, or sticking of the intake valve.
Because gasoline will volatilize before entering the intake
valve if the temperature of the carburetor tube is high, gum
content will remain on the walls of the intake pipes. Although
this will not result in serious damage, when the temperature is
low, this residue will adhere to the suction valve, after which
it will carbonize and causes damage.
For this reason, it is best to use a gasoline with a low gum
content.
