Not on my bike but on a snowblower that I am trying to set the main jet and the idle jet that are accessible externally. Without taking it apart I thought there might be a good cleaning agent that I could put in the fuel that would make sure they are reasonably clean. Can't seem to set the jets the way the instruction book claims I can.

Shep,
If you can't get a good adjustment on these adjustable jets, that suggests they are already plugged or sludged up and the best way to deal with them is to remove and clean them. There is any number of carburetor cleaners on the market which might work satisfactorily and may clean the jets and other carb passages when added to the fuel, but removing and cleaning the components in question gives the most immediate satisfaction.
When I did the carb on our CB125 project bike, I used toluene for cleaning (after the commercial carb cleaner was tried). That carb was a real mess inside and the toluene dissolved the crud quite well. I still have some and am willing to share. ...or it's probably available anywhere paint is sold - mine came from Home Depot.
I wouldn't suggest adding toluene to the fuel as I'm not sure what effect it may have on some non-metal parts (gaskets and O-rings).
If I can help, let me know.

Thanks Theo. I will start with pulling the jets and cleaning them before pulling the complete carburetor off.
This snow-rain will probably melt on it's own.

After the toluene (xylene does the same trick) bring it up here an I'll put it in my ultrasonic cleaner.
