Mechanical removal of clogs from dried petrol is only method that works because spray carb-cleaners are now just weak carrier solvents that no longer have chlorinated compounds. Such as trichloroethylene, carbon tetrachloride, or chlorobenzene. Which provide real cutting power to break poly-vinyl bonds in dried-petrol clogs.
There are many, many folks who can re-build entire engine using just their teeth with both hands tied behind back who've had to pull carbs 4-5 times to do ever deeper and more thorough cleaning until it was factory-fresh clean. Or you can send them to ducatiman to get it done right 1st time!
