I have problems with two stroke carburetors which I often end up solving by buying a whole new carburetor and replacing the old one. I think that somehow the orifices get clogged.
I have tried disassembling them and cleaning them in an ultrasonic cleaner, but it does not work.
Is there any way to test a small carburetor and make sure all the orifices are clear? The problem is that when I look at the carb it is basically a block of steel with a bunch of different holes in it, and it is not clear to me which hole connects to what so I have no way to tell if it has a blockage or not.
