Also, not sure about dying when you drop throttle. Be sure idle is set correctly. ~1500RPM with a hot, fully warmed up motor. If you dont have a tachometer, 1500 can sound a little faster than what you might think.
Too tight valves can make it impossible to get a good idle. Few things I've learned along the way...
Set clutch freeplay COLD.
Set valves COLD.
Set idle HOT.
Be sure to watch that video. Carb tuning should be done in 3 steps...
Idle (pilot jet and screw)
Top End (main jet)
Midrange (needle)
