Picked up a 2000 XR50 that had been in storage for several years.
Replaced the clogged petcock, dump some fresh fuel in there and it runs, but acts like it has an air leak. The idle stays really high, until it drops down enough to just stall out. Riding it is far more exciting than it should be, as chopping the throttle does not result in the rpm's dropping down right away. Throttle cable is fine.
Picked up a Honda carb rebuild kit, along with the 3 o-rings that go between the head and the carb. Replaced the gasket in the cap. Dismantled the carb and let it soak for hours in Chemdip. Same rpm issue.
Put some Hondabond between the head/intake/spacer/carb, put a thin layer of grease where the dust boot goes into the carb top along with a bit on the screw top gasket. A touch of grease on the fuel screw and idle screw threads. No change.
Spraying brake cleaner at the various intake and carb points while it's running seems to have no effect.
Suggestions appreciated.

I've tried the fuel screw anywhere from 1 to 3 turns out. All the way in causes the rpms to climb up I've noticed.
Bike is stock, and low enough hours to still be on the original tires. I also replaced the air filter with a new one.

Well you called it Paw Paw. Clogged pilot.
Unfortunately, no amount of air pressure, carb cleaner, Chemdip, and welding tip cleaners could unclog the circuit. I thought it was clear of obstructions; but clearly I was wrong.
$13 for a Chinese carb and it's running like a top. Although it's supposed to be a carbon copy, it's not. Very similar, but not the same. Still, bolting it up and using the included slide resulted it a perfect running XR50.
