My 1989 Honda 125 4 Wheeler Will not idle when it gets hot.?

[Bo W]

i have cleaned the carb bowl and also checked for good fire on the spark plug(I also brought a new one two days ago.) but it will idle when it's cold but not when the engine warms up. also i have tried adjusting the carb. plus it gives no respond to the choke when it is on or off. i knw the choke works because i have looked into the carb while moving the choke lever and the choke flap moves. Could u please help me?...Cheers!

Hmm, possibly your choke return spring needs changed or the needle and seat are worn out, but I am just geussing at it all the way from over here, sounds like that anyway.
