.15 CVR-x question?

[ShadyOne]

I have been running this OS .15 for about one gallon now and recently got it perfectly tuned. My question is that at idle this motor spits an extreme amount of gas out of the exhaust, the motor idles great has great response and full top end power, is this something i should be concerned with?

That's just unburned fuel. Nothing to worry about, just means your idle is set on the rich side.

When I break in new engines, I always have a ton of green liquid coming from the exhaust pipe. All caused by running rich.
