A lot of the guys at my field have the big cordless drills. Some are geared and some are just high voltage. Easy to set up with the spinner cone. When I have one of my bigger gas engines at the field and it doesn't want to hand start I have borrowed them more then once. Harbor Freight has the drills and the battery packs. 18 volts works pretty good with most starters up to 30cc. After that a few more volts is a big help or one of the geared drills.
