Joe Gibbs stuff is good. And yes prime the carb and the engine as Ron described. Turn the mixture screws all the way in and then back them out 1.25, I like to turn the idle screw up before starting the engine. Have your timing light already hooked up, run the rpms up to about 2200 and set the timing at about 34ish. After break in you can set your actual advance and idle mixture screws.
