A couple things about the edelbrock carb...
The fit between the carb and the included intake manifold is very tight, you will probably have to mess with it for a while in order to get it just right so it slides in all the way. I messed with mine for 15 minutes when I installed it and a couple days later discovered I still only had it slid in about halfway. It will be much easier to leave the airbox off completely until you're sure you have the carb secured in the manifold all the way.
The second thing, my only real complaint about the edelbrock, I hope you don't like riding in cold weather too much. I rode mine in the winter like a snowmobile, and mine consistently pissed me off because for whatever reason, the carb doesn't have a choke or enrichener circuit, so when the engine is cold you'll have to fight it for the first couple minutes to get it fired up and keep it idling. Once it gets a little heat built up it performed fine, getting to that point was tricky for me, especially when the weather dropped below freezing. I really don't understand why this carb doesn't have a choke but every other carb ever built in the history of mankind has a choke. I even raised hell with edelbrock about it and they told me that a choke wasn't necessary on the warrior. Bullshit.
