I had no problem cleaning the needle jet piece and the orifices. When I go to use the ultrasonic cleaner I fill it with a 4:1 solution of Simple Green and water. I let the cleaner heat the water up to about 50-55 degrees C with the parts already soaking in the solution. Once everything is good and warmed up, I turn the ultrasonic cleaner on for a 20 minute cycle. I don't like the noise this thing makes so I always leave the room and work on something else. Therefore, the parts have a tendency to sit in the warm water for quite a while after the cycle ends. When I return, I pull the parts out and squirt through all the orifices with WD40. I personally feel that WD40 isn't the panacea of cleaning solutions but for temporary light cleaning and lubing it works. If it doesn't seem that all the openings are good and clear, I'll run the ultrasonic cycle again. These carbs were mostly dirty from old dried up gas and oil. During disassembly I had the most difficulty in getting the slides out. They seem to be pretty delicate so I don't use metal tools to try and move them up the shaft. I use a lot of penetrating oil and sometimes run it through the ultrasonic machine partially assembled in order to loosen parts up. Interestingly enough, I guess a previous owner had been in the carbs before as the choke plunger spring was missing in one of the carbs. Hope this helps.
