A fellow had a handheld stihl bg55 leafblower yesterday that he had somehow modified so that it would start with just one pull on half choke without pumping the primer bulb. Anyone know how this is accomplished? The way it was rigged, if you did happen to pump the primer bulb, it flooded it. He wasn't there long enough to explain what he did, but this is what I need so my wife can start and use the blower, weed eater, chainsaw, etc. whenever she wants to and I'm not around to start it for her. Any help would be appreciated.
