My trencher finally breathed it's last, and I'm pleased, because now I can get rid of that troublesome 440 engine. I'm replacing it with a standard electric start GX390, which was recommended by the machine manufacturer. It's pretty much a bolt in, but I have to add a battery tray, the 440 was pull start only(No idea what engineer thought that was a good idea) The battery wiring is simplistic, as the 390 is self contained, one wire to the coil, one to ground, turn the key and off you go....
