Remember the type  of fire  that you are putting  out  .If  you  use  a dry
powder ABC  or BC  or purple k they  are  a  powder (that is in  caveman
terms fine  granular ) I  use a Halon extinguisher this takes out the
oxygen from the  fire not  mess to clean  up  nothing  to  get into your
carb or  air filter  to  get into the  system.
they cost more  but  well worth the  investment.
