please set your mind to thinking how to convert to electric start the d#$%&m gas mower or gas trimmer, weed wacker things that are so impossible to start for those of us like your wife.

If the reader isn't already one of these, or chooses not to aquire one, the solution may be this: Many modern small gas engins have a priming bulb in the fuel line. If you follow the directions and only depress or squeeze the bulb three or four times, it's harldly ever enough. Instead, work the bulb until you hear a squirting sound inside the device. That signals that fuel has reached the carburator. After that, it's a one or two pull deal.
