Carb cleaning
A forum member suggested to use Gumout, spray it in the main jets to clean the carb. I haven't done it yet as the carb has been performing pretty well. Today I took off the filter assembly and did notice some grime in certain places. Should I go ahead with the Gumout or is there a better way without the need of taking it apart?
If Gumout, where exactly do I spray it, how much and how long should I run / drive the car?
Thanks

Spray "Gumout" is really more for cleaning the outside of the carb than the inside. Gumout also makes a fuel additive that is meant to clean the inside (well, jets, rods), but that's pretty slow...if you want it done 'now'.
To clean a carb properly, you need to disassemble the carb and dunk it for a few hours in some carb cleaner...that will get rid of the residue/build-up in passages, orifices and on part surfaces. But, if the carb is working well now, that just doesn't seem necessary at present.
Why not put some carb/fuel system cleaner (I like SeaFoam, myself) into a tank of fuel and let it clean itself out over the next few weeks. You can also spray the gunk off the outside of the carb to make it look better. The linkages will also free up and operate better once they have been de-gunked, also.

In my 1976 Corvette I find that I need to use fuel cleaners in order to keep the engine running well. Some suggest that problems happen as a result of newer fuel types. I do find that in my Corvette that it noticably runs better with cleaners in the fuel. My motorcycle needs it otherwise the carburetor gums up fast then idles poorly. Even my snow blower runs poorly unless I put the cleaners in.
My fuel injected vehicles don't seem to need the cleaners.
