    Well of course #1 is does it bolt up and fit and can you make the throttle work. Remember the throttle is synchronized with the spark avance.

    #2 is size of venturi (the big hole through the center) Too small will reduce horsepower, too big may run totally lousy.

    Those are most important parameters. Otherwise, have fun.
