Intake cross over blockage or not ?

I have mine open on my RPM intake (non air gap) and it's nice because it warms up fast enough so that not having the choke hooked up works out ok. I just feather it and keep the rev's up for about 30 sec's and she settles down. A good carb will help make up the difference on warm up too. That's what I've found anyway...

On the flipside, it does work as a hotbed under the carb for putting extra heat on your fuel, which is never good from a performance and efficiency standpoint.

One of those pick your poison things I suppose...
