Spraying Powertune into the the throat of the carb does nothing to clean the carb. All it does is go straight into the engine. Good for decarboning the motor but does not clean any of the jets or passages in the carb. Be carefull with trying to run a fuel additive to "clean" the carbs. If one of the high speed jets is plugged it will make that cylinder very lean which is not a good thing. If the carbs need to be cleaned have them taken apart and cleaned.
Hi again,
The extra cleaner sprayed into the throat of the carbs will work into the float bowl, dissolve particles of varnish there or through the reed cage. As far as jets go, you are correct in that the cleaner will not get to them, thus the added amount to not only stabilize the fuel, it will work to clean the jets as well. You are also correct that the engine will be decarbonized well, which, if never done before will increase power, and smooth out a rough running engine to some extent.
For the little bit of time the decarbonizer is running, one will not damage a cylinder if a jet is plugged. If a jet is plugged, the engine would run horribly upon throttle up to the point one would not feel comfortable running the motor at a high speed....it would sound horrible, and would peform horribly. And..chances are, throttle up would be a dog. The decarbonizer would not even have a chance to run a cylinder lean to the point of damage.
I would also agree, that if the motor will not get good power upon throttle up, a good tear down and cleaning of the carbs will be in order.
