Oh ok. Thats normal for it the choke to go wide open. It would make sense you'd have to hold it closed :-) Well if it wants choked to run, then you have a nice vacuum leak somewhere. Check around the top of the carb and you'll see the small black vacuum line.. make sure it hasn't popped off. You can remove the 2 bolts holding the air cleaner to the carburetor to gain better access - beware though, those also hold the carb to the intake plenum.
