Disconnect the flat linkage attached to the jet nozzle & see if that allows the nozzle to slide up & down smoothly.The linkage occasionally needs a bit of a twist to align perfectly with the bushing & screw. Slide the nozzle up & down with & without the jet needle in place & do the drop test on the piston to ensure the nozzle is aligned with the jet. Lube tho outside of the jet nozzle before reassembly.

I concur.

 

I like to remove the jet and clean with a scotchbrite pad or fine sand paper.

 

Spray the tube where the jet slides with carb cleaner

I also have a problem pulling out the nozzle it seems stucked. Can I immerse the whole carb in a can of chem dip? Hoping it will unstuck  I need some expert advise. Thanks

I'm no expert but when it happened to a set I bought I disconnected the hose and twisted the nozzle until it would pull out. It just old gas/ varnish that has it stuck. Pull the hose and slowly turn it until it loosens up.

Oh yeah unhook the choke arm. Unhook everything and twist it.

You could also shoot some carb cleaner with the little red straw if they're bad gummed up.
