the rc valve has nothing to do with the start, its should be around the pilot jet/slow jet or the spark, the standard spark use 9 series.
the rc valve should move when you switch on the ignition, but sometime its doesn't, depend on it's position when it got turned off. try to start your engine and play the throttle, it's should be moving like nsrjb said..... if it's not detach the cable and try to turn your rc valve axe by hand, if its hard that's mean you have dirty cylinder (on the rc valve) you should clean it. but if its light and thats mean something wrong with the CDI or the motorservo...
