Lisle 20020 Limited Access Spark Plug

A must for your old Beezers, Triumphs, Nortons, Harleys, in fact anything that takes a 14 mil plug. Left my '83 Ironheads plug threads looking brand new.

Quality made. Threads in perfectly and a must if the plug does not install smoothly. Thread it in with grease or some form of anti seize. Great to ensure your mating threads are clean. Not designed to cut....it cleans the threads. It is the perfect size to reach deep holes.

Worked perfectly on my SCAG Tiger Cub

I'd inherited a Toro z4200, and when I went to replace the spark plug it would seize halfway on entry. It still worked, but I looked at the old one and noticed it was only in halfway as well. Someone, at some point, had to of messed up the threads inside. I looked, and they were bunked. No clue what to do, I mean it worked, but it should be able to insert fully. Is this something I need to take to a repair shop? Will it cause issues? I didn't want to bore it out and use one of the kits that you had to insert the extra piece, pretty sure I'd screw that up and make things worse. So I found this tracer, and ordered it with the Loctite 37539 Silver-Grade Anti-Seize Lubricant Tube - 1 oz. as it said 'Important: Use Anti Seize" in the description. It arrived today. I removed it and the lube from their packages and put some lube on the tracer. I removed my old spark plug that was half inserted, then used a ratchet attachment on my impact drill and slowly ran this through the treads, backed it out, and ran it through again. I wiped up any excess lube, blew out the hole with an air compressor, and put the spark plug, now completely in place, back into the hole. It was that easy, maybe took 5 minutes from opening the package to having fixed spark plug threads. You're most likely not supposed to use an impact drill, but I was careful and it worked out great. That way I didn't really have to fight with it at all tugging on a ratchet. Now the mower connection with the spark plug is so good that I don't even need to put the throttle in choke to start the mower, just turn the key, even on turtle, and it's over in like half a second. This is a great product, and was worth the 5 bucks any day.

I somehow buggered the lawn mower thread hole, used this along with anti seize lubricant, tool worked well.
