These carbs dont have diaphragms, they are all metal slides, which is really nice.
I would have loved to use an ultrasonic cleaner, but in addition to the problem of not having one, the clogged pilot jet is pressed into the carb body and I dont see any way to remove it without damage and I dont think the whole carb would go in the cleaner very well. I would have also loved to use the E string trick, but the port that's clogged runs horizontally between 2 vertical holes. I tried getting a wire to poke in there, but didn't have any success. Regardless I pulled it out of the dip today at lunch time ( after soaking all night and morning) and finally I'm getting some spray through the pilot screw port so it looks like it's actually working. I went ahead and dropped it back in and will get back to cleaning and reassembly tomorrow. Hopefully that'll be the end of this particular issue.
