The most common cause of annual mower repairs results from leaving gas or gas-oil mix inside the engine's tank and carburetor over the winter season. Avoid expensive service shop charges by either 1) running the engine until all gas has been used up, or 2) adding a commercially-available gas stabilizer to the tank before putting the mower away in the fall. A $3 investment may save you a $60 repair bill.
To get professional-looking splices in wiring without electrical tape, try head-shrinkable tubing. Slip a tube on one of the wires before splicing. After splicing, move it over the splice and apply heat with a heat gun. The tubing will shrink down for a neat, protective covering. You can buy tubes in multiple sizes, as well as shrinkable wire caps to use in place of screw-on wire nuts. They’re perfect for work on vehicles, trailers, underground and pool wiring, or for outdoor lighting or sprinkler systems.
