great tip will have to try that! at work we also add 1 ltr dextron to a fuel tank for our kenworth heavy trucks with 550hp cat engines every 3rd or 4th fillups when they start to run a little rough smooths them right out! another trick an old timer taught me [and yes there is some one out there older than me lol] to clean valves is
[1] warm the engine up and remove air cleaner
[2] rev up to aprox 3000 rpm
[3] pour a little water down the carb engine will sputter/cough and sound like its going to blow up wait till it smooths out and do 2 or 3 times
the cold water hitting the hot valves peels the carbon off like butter
i didnt beleive this untill i seen it my self and it works! that engine realy purrs now
my freind is a mechanic that had a local 2 bay garage for over 30 years and shown me lots of these kinds of tricks [did this to my 460/78 f350 sc last summer

It's the steam that actually cleans up the carbon deposits, instead of pouring the water i prefer to fill a spray bottle and mist the water over the throat of the carb as i work the throttle, no risk of hyrdo lock and bending a connecting rod with that method.
