Working on a Dolmar MS 22 C trimmer with a brush blade for a friend. It has a TK carburetor. I opened the carb, cleaned and reassembled and it ran pretty well. The next day it wouldn't say a word. Sprayed some starting fluid in the throat and it fired and ran then died immediately. In the cleaning, I did not force the little diaphragms off (they seemed very stuck on) but I removed the needle and cleaned it as best I could. I checked the tank vent in the fuel cap and it can breathe. It has no adjustments other than idle speed. I need guidance, maybe a source of parts to rebuild it. I have not worked on this brand carb before, worked on may others. Any help would be appreciated!

My best guess would be to replace the diaphragms. And from looking at the exploded view there appears to be a filter that may be behind a diaphragm. Maybe a clogged filter? https://www.jackssmallengines.com/j...trimmers-brush-cutters/carburetor-air-cleaner
TK carb not very common. Attached is some info on the carb in a Toro trimmer. It's the only TK carb info I have seen.
Thanks for the info--I did see the little filter, did not disturb it so I will go back and make sure that it is not plugged. The exploded view of the carb may be the key I need to be sure all the parts are in the right order. I'm convinced that SOMETHING is not letting the fuel get into the cylinder. I have now run the carb through the ultrasonic cleaner twice.
