i just got this engine built and in the car, but whenever its cold, it has a hard time starting on its own. It takes a few times, and also some extra throttling in order to get it to start. Once its started though, it idles beautifully on its own.

The only reason i could think of this problem occurring is due to the piston rings not having settled in nicely against the cylinder walls yet... or the fact that its running un-tuned at the moment. What y'all think??
