hot start plunger and nut where it goes into the carb... have heard the plastic nuts crack easy and or threads strip... have also heard the plunger can stick..
fuel tank cap and vent can clog and not deliver fuel ...(have actually had one do this)
make sure #11 in this picture is in correct and not cracked.
sure sounds like a pilot jet/passage issue to me, but i am sure no expert....
hope you find it..

have not had much luck cleaning clogged pilot jets, but you said you replaced it also...

May want to check your valve clearances and make sure that your carburetor boot is not loose or cracked, as well.
for sure on valve clearance.... can sure make them not idle....

My thoughts, exactly. If the bike ran good before and the carb is clean, then something isn't assembled right. An upside down slide will have the symptoms of a too small or clogged pilot jet.
Check the slide plate and make sure you did not assemble it upside down. The plate goes on the engine side of the slide with the cutout facing down.
