Kemp,

Your idle needle is probably set to low. With my Sirio it idles great when cool but once the temp gets up a bit over 225 the idle will drop down a bit and sometimes the engine will die out so now I run with a bit of a higher idle when cold and once it gets up to temp its fine. Also, what plug are you running? With the cooler temps we've been having a 6 or 7 plug is a bit to cool and the engine may have trouble staying lit at idle. You can drop a shim or go to a hotter plug. I went to a #5 plug and haven't had a problem.

Regards,
Daniel
