After a shop cleaned my carbs in an Ultrasonic Hi temperature cleaner I found the pilot circuit still plugged on one carb. The guy in the shop suggested a 50/50 solution of Muratic Acid and water. A slow process of dribbeling this off the end of a choke cleaner tube every time the hole opened up and quit bubbling. I finally tried squirting brake cleaner thru it again after about three hours and it was no longer plugged. If this disolves crud in carbs, why not soak them in it? You would use about a dollars worth of acid, ALTHOUGH very dangerous stuff to work with! Also will rust everyhing in the room if you use enough to clean oout a tank, as the shop owner showed me the rust on his drill press, etc! Another question I have, is why some carbs have a jet in the threaded hole, mine have the port buried inside?
