I have about 1500 mi on my machine and it haves a problem with idle when cold. it runs good warm but can be hard starting when its cold and wants to die. if you start it and give it some gas to get it moving and not let up on the gas it will run fine. let up on the gas and it will die. be hard to start but if ypu let it warm up for a long tome it will be ok. anyone ever have that problem??
