JND Fool-Proof Engine Ignition Spark Tester

Model: Fool-proof Engine Ignition   |    Mpn: 1249   |    Ean: 3021772012494   |    PartNumber: 1249   |   Asin: B0042KJV9U

Worth it's weight in gold when a 2- or 4-cycle gas engine won't start, because the first thing you need to determine is whether the problem is no-spark/ignition or fuel supply/mixture. We were fooled ONCE into using a screwdriver to make the spark jump from the cable; DON'T try that at home - it hurts! This great little tool is the no-shock way to get the answer on ignition in about 30 seconds - BEFORE you work yourself to heart-attack stage pulling the rope on your lawnmower/chainsaw/snowblower or burning out the starter. Especially useful since many small engines now have low-oil cutoff or other ignition breakers. Rust-resistant chrome steel shaft, virtually unbreakable polycarbonate body and flexible rubber boot & cable. Internal bulb will last for years but is replaceable if necessary. Dimensions: 6" boot/cable, 5" shaft/light housing; 2.2 oz. Universal fit for all 2- or 4-stroke, single or multi-cylinder gasoline engines.

Features

  • Must-have diagnostic tool for any engine with a spark plug
  • When engine won't start, gives instant answer to 'does it have spark?'
  • Simple to use - just remove rubber boot from spark plug, insert tester & place tester boot on plug
  • Turn the engine over - if ignition is being sent to the cylinder, light in tester glows
  • Great time and frustration-saver with cars, motorcycles, boats, chainsaws, lawn mowers & more

Package Included:
25 Thread inserts
1 Lug breaking tool
1 Installation tool
1 wrench
1 Thread tap
1 Drill bit

Features

  • Drilling - clear the damaged threads with a standard drill. (to repair a spark plug thread no pre-drilling is necessary if using the special spark plug tap), please pay attention that for fluteless taps bigger holes are required.
  • Checking - check that the thread and pitch of the tap and the bolt match.
  • Tapping - use the special taps for cutting the holding thread into the cleared hole (recommended to use a suitable cutting oil).
  • Install the insert - place insert on installation tool and position the adjustable ring so that the insert tang is centered in the tang slot. Wind the insert in with a light downward pressure until a half turn below the surface. Don't work against the thread direction as the tang could break.
  • Tang removal - After finishing lift the installation tool and use the tang break tool to remove the tang. For bigger sizes and spark plug taps use long nose pliers to remove the tang. Due to the narrow and exact tolerances the new thread normally is stronger than the original ones.

NGK Spark Plugs are designed to operate over a much wider heat range than ordinary plugs. They resist carbon buildup and pre-ignition. Each features high alumina ceramics for better heat transfer and electrical insulation. A patented triple gasket sealing process eliminates the possibility of combustion gas leakage, and a longer insulator nose prevents fouling and misfiring. A solid copper core and its nickel tipped electrode provide a longer plus life.
