Cold natured Raptor 50

This little machine has to sit and warm up for a very long time before it will take throttle or even pull itself without dying. Is this common for the raptor 50? I am thinking a dirty pilot jet but it runs good when warm after 10 minutes or so. Also the previous owner says that it has a new carb on it and the carb does look clean enough to be new. Any thoughts or knowledge out there on the smallest raptor?

Yeah, sounds like a pilot jet with some trash in it. Doesn't take long for ethanol fuel to work it's magic.

How's the airfilter?
