Loong jumper test cables.
Size: silicone wire red 25ft and black 25ft, Color: Red and Black
Over-kill makes nice tools. This is good tinned fine stranded wire with quality silicone insulation. Five-star stuff, without buying some expensive large quantity minimum from a high-end wire manufacturer.

Honda product and quality.
Do NOT understand why my lawnmower with a Honda engine did not come with a Honda carburetor. Replaced with this Honda carburetor and starts easily. The other carb only lasted 1.5 years.
