What is the spark plug gap on a Honda lawn mower?
The gap should be 0.028 ~ 0.031 inches (0.7 ~ 0.8 mm). Correct it if needed by bending the side electrode. Step 6: Install the new spark plug by hand.
Keeping this in consideration, do Honda lawn mower spark plugs come pre gapped?
Champion spark plugs traditionally leave the factory pre-gapped for their most popular application. However, a plug may fit hundreds of engines, from cars to golf carts. Gapping the plugs to your engine's specifications is important to prevent pre-ignition, detonation, fouling and poor fuel economy.
You'll need a spark plug gauge to adjust the gap on your lawn mower's spark plug. Although many small engine spark plugs require a .030 gap, this varies depending on the engine type.
Simply so, do lawn mower spark plugs need to be gapped?
Depending on the type of spark plug needed for your lawnmower engine, the gap between the post and tongue (center and ground electrodes) must be set a specific width. If the gap is too large, the spark generated in the center electrode will not travel completely to the ground electrode.
What kind of spark plugs does Honda use?
Here's how a standard OEM Honda plug is constructed: Platinum or Iridium Center Electrode. A OEM Honda plug will have a platinum (90k mile rating) or iridium tip (120k mile rating). These are both costly metals, but prolong the life of your plug.
