Scooterotica

Hello, noticed 2 stroke oil p***ing down the back of my recently aquired P2, removed carb and carb box cleaned up and replaced gaskets between engine and carb box and carb, still doing it and now it wont tick over at all , standard set up except simonini and 120 main jet, bike runs smooth but wont tick over ( wound mix screw and tickover screw to factory set) little difficult to start too?? Any ideas blokes?, dropped oil, no fuel in it.

check tickover screw has a point on it, point is good and round is'nt. check slide is'nt worn were tickover screw contacts is'nt worn. if ye scoot fires up ok with choke and dies when chokes pushed in, definetly ye throttle slide needle(tickover screw) or slide worn
