Cleaning the injectors from the outside usually does little good because spray pattern is determined more by internal contamination. Rarely are the deposits on the outside. Running a PEA based cleaner (Techron, Gumout Regane) through the fuel system does most of the cleaning the injectors will ever need. If you want to pull the injectors and clean them you could rig up a system such as this, but this kind of cleaning is only really needed if you are having known injector issues.
is the carb cleaner bad for the internals of the injector? like wouldnt it dry them out too much because of the harshness of the chemicals? granted gasoline would have the same effect on a lower level but isnt it bad for it?
