about 30 seconds in when it finally starts there is a "honk" kind of sound like a valve finally opening or something when it starts. Once started it runs great, I can even shut it off immediately and it will fire right up, it's only on a cold start when very cold outside that I have to crank forever to get it to fire.
Any ideas? It has to be related to what ever makes that honk noise
