Restoring lawn mower spark plug threads with Sav-A-Thread by Helicoil

[@sosunnycanmakeitright]

This was so helpful. Gave me the courage to try it. Thank you

It you bring the piston up to tdc and then back it down to accommodate the tool, pack the inside with a paper towel it will act as a block for the shavings should any get past the grease. After the rethreading you can stick a shop vac over the hole and suck out any free shavings, then use needle nose pliers to pull out the towel. The leftover grease around the ring of the hole will get pushed out of the way by the towel coming out too. It's sort of a belt & suspenders solution to avoiding swarth in the piston.

Nice video! I think that Heli-coil is the one of the easier kits out there. You saved that owner a lot buy not having to remove the head and possibly machine shop work.

Thank you Lawnmower Lady! Very true, and good insight. Thanks for sharing!

@@kbssmallenginerepair2615 Thanks for the shout out. I subbed you channel.

No matter how much grease, or how careful you go about it, you MUST BLOW IT OUT with air. I have a blow gun with a long skinny nipple that last thing, I stick it in the spark plug hole and blow it out very well (Compressed air, of course). Safety glasses required! You will be amazed how many small pieces blow out from inside the engine, you can even see it on this video. Blow it out real good! Also I let my red lock tite set for a couple of days before I fired it up.

Good fix and explanation of process. Always hate having to do this.

[@kbssmallenginerepair2615]

Thanks Rusty!

[@kbssmallenginerepair2615]

Thanks Dr.! What is your thread repair brand choice? Is there one you always go to, or do you just get whatever you can? Hope you and the family are doing well!

Absolutely!

Job well done again mr.

[@kbssmallenginerepair2615]

Thank you Henry! I appreciate your feedback!

[@aboutdoorequipmentllc7097]

I have a spark plug that I cut 3 grooves in the threads with a drimmel or grinder to use as a tap. This will act as a tap and clean up the threads in the head. almost 100% success rate. no need for the heli coil.

[@hackrichards4824]

Thank you kindly!

[@maxvolovich9407]

The actual reason why you want to back off and brake the chips off when tapping a hole is so you dont jam up the tap and prevent braking a tap removing removing the hardened tap makes it a bad day for a mechanic! Lol

[@mattshobbyshop2703]

Nice video KB

[@kbssmallenginerepair2615]

Thanks Matt!

[@billlovett4256]

Great video, have you ever used a piece of hose conected to a spark plug to start them into their hole when awkwardly deep inside. Useful on some snowblowers too. I think it's 3/8 ID hose.

[@kbssmallenginerepair2615]

I haven't, but I have heard it mentioned before. I'll have to give it a try sometime.

[@rosemarygonzalez7778]

Do you leave the black piece in there? This is my first doing something like this.

[@JungleBobRepair]

Nice video

[@kbssmallenginerepair2615]

Thanks Jungle Bob!

[@philliphall5198]

Have you had one come lose yet, I’m thinking just pull head and change them for there mistakes

[@Lovinflyindrones2022]

How much does a job like that cost the customer?? Normally

[@kbssmallenginerepair2615]

I charge $80 for a spark plug restore.

[@Lovinflyindrones2022]

Does the heli coils last a long time

[@kbssmallenginerepair2615]

Yeah, typically they will last just as long as any other threaded part of the engine, as long as it is taken care of and not cross threaded or over torqued, obviously.

[@maxvolovich9407]

MR! where is your safety glass. Trip to the hospital is not fun when you have to pay for it at the hospital.

[@kbssmallenginerepair2615]

Yeah, that was not good, which is why I had to put the caution label on the screen....dumb mistake.

[@maxvolovich9407]

@@kbssmallenginerepair2615 not a dumb mistake! I will never use that word! It is not hard when you get tied up and busy. It happens to all of us

[@michaelrockwell9691]

I never wear safety glasses and still have most of my eyes.

[@christopherlabarge6364]

we can see the chips no need to be so close to the camera!
