Maybe with the colder weather you are too lean in the pilot jet. Or the jet just might be dirty or clogged.

Pilot circuit might be clogged. Clean the carb, using the correct solution, not automotive spray carb cleaner, which can damage rubber components.

Keep messin with it till you can get it really well warmed up then see how it runs, no need to crack the throttle real hard till it's hot. And I agree with kx02, weather changes can have a strong effect on jetting especially two strokes.

thanks for the info .... its not too much colder than when it ran ok .... just must be a clogged jet ?? thanks again ....

it also could be loaded up, just warm it up, ride it

clean the pilot jet. DO NOT stick anything in it. use cleaner and compressed air. That hole is so small. I have seen many people think they could even use a torch tip cleaner...they ruin it everytime.
