Centrifugal clutches are what our old skool mini bikes & go-karts with lawn mower engines had on them.
If you are talking about the HT engines, that is not always true. The GGG-1 cannot be bump started. It does not come with a hand clutch. I have never seen one in the USA. All of the dual start GGG-2 engines with centrifugal clutches, pull starts and hand clutches can be bump started or pull started. Most of the retrofit centrifugal clutches for the HT engine have the one way bearing that allows it to be bump started.
