If it's a JOHNNY-RUDE, then you unplug the harness from the VRO pump and cap off the oil line(the small inlet on the small side of the pump). Many people just put a bolt in the hose to block it off, or you can go to a dealer and they sell a special heavy rubber boot to cap it off. And make certain to pre-mix your oil from then on. I also like to make sure that the pre-mix is what's in the bowls as well before starting. If you disconnect it and put pre-mix in the tank, you could still have plain gas in your lines and filter. So I would drain your bowls and filters and pump tyhe pre-mix through those as well.
