Kerosene doesn't come pressurized in a bottle. And carb cleaner cleans wickedly fast and accurate. It gets everything out on the inside of the links as well as the outside in a matter of minutes with no scrubbing. Priceless for time it saves and the work too. As long as it's rubber safe that is.Time to search the internet looking for answers.
Most carb cleaners are not rubber safe (which is why you have to replace all gaskets and seals if you use the stuff). The only exception I know of is yamaha's carb cleaner, which comes in a liquid that you mix 1:3 in gasoline. That is to say, the only rubber safe carb cleaner doesn't come in a spray.
