There are, of course, several successful or almost that good starter techniques applicable to older Aircraft. The Hamp drill motor thing is one of many. But the McDowell starter doesn't require a hand drill, a battery and has at least 75 years of use history in Aeroncas, Taylorcraft, Luscombes and maybe even in some coupes. If you are interested in seeing it in action, search for McDowell Starter on You Tube and you will find a very convincing demonstration of one in an Aeronca Chief by Colie Pitts.
