DIY HeliCoil Chainsaw Repair Stripped Spark Plug Repair Sav-A-Thread Kit without Cylinder Removal 

Good video sir. I saved myself from having to buy a new 460. I did have to use an o ring pick with grease on the end to get out a few stubborn chips but other than that it was a simple process.

After watching almost 10 videos about how to re thread a spark plug into my lawn mower I came across yours and I said thank God finally somebody that knows how to do it explain it keep it nice and concise and go about their day and give everybody a great video without a bunch of BS my hat's off to you

Very nice. may I ask how do you know what size kit go get. I want to fix my Stihl ms251 and would like to try this.

I don't see why you would need the ultra black sealant if you set the insert below flush level. I would think the spark plug would seal anyway.

Good video and a nice long one after a long hiatus. I had the same thought about threading in the spark plug when you weren’t getting the insert in. Not cheating at all in my opinion.

Just did an MS261 with your method....flawless....thanks for posting this.

Would it be possible to open the exhaust port then connect shop vac on the port then it would pull the chips thru the tap flutes and out the exhaust.

Awesome video! Super helpful since these don't come with even basic instructions when you buy them.

Hey bro you are a lifesaver thank you for the video

thank you for the video i'm getting the same kit you got only thing in canada it's costing me $55.00

Maybe stuff a shop towel down the plug hole and prevent even more shavings from falling in, then pluck it out with long nose pliers.

I would advise taking the cylinder off its not a risk i would take its easy

Great tutorial on installing the save a thread kit. You are a super good coach for guys like me that want to learn how to do my own repairs . Thank you!

Thank you so much for this video, my son and I just fixed our ms-391 Stihl chainsaw all because of you. It is well explain and clear sound , totally useful, we just save a bunch of money by doing it ourselves, 👍👍👍👍

Thank you! Followed your instructions to a (T) worked well for me in the same situation.

Nice video. Thank you for sharing. Just thinking. Would that silicone gasket maker stop a minor air leak at around 130psi. I would have thought one that hardens may be better. Hopefully someone can answer for me. Cheers

Just completed my first repair. I found that the original threads were so badly damaged and mostly broken off and missing that the tap struggled to go in straight. Once it got in to the tapered potion of removing just before the insert threads began it did not have any original thread to hang on to. The tap at that point simply fell loose and was somewhat tenuous to get the tapered cut to stay perpendicular. It finished but was not what would be a perfect perpendicular alignment, but it worked.

Thank you for this very nicely detailed video and excellent explanation. My question would be, what is it that people are doing to strip out a spark plug hole in the first place? I've used chainsaws and other small engines for a long time and I've never stripped a spark plug hole.

What size do you use? I bought 5334-14. For Stihl 211 that fits a NGK CMR6H. Can I make the hole bigger and use a different sparkplug?

Good video and good technique

Nice video. Question: Is there a separate kit for each size of spark plug hole? I know Stihl, for example, has at least 2 diameters. Thanks

Thanks.

How do you know what size inserts to buy? I have no idea the size of my spark plug.

should have used red Loctite to install insert...silicone wont stand the heat.

what grease do u use because imp doing it on my john dear snow blower and I wanna maker sure I do it good first try even though I can only try it once I think?

Learned Alot thank you friend

Couldnt have found a better video for my application...a 660, with lots of hours and a stripped out plug...same exact kit. Never used a helicoil...lots of thread chasing and use of taps and dyes over the years ( i might be hard on shit...but i am pretty certain i somehow end up withfactory defective stuff🤔) defective) I really appreciate you taking your valuable time to help out those of us that can only afford to attack our own projects! I would really love to say i have to leave the head on for some reason...but laziness is really the excuse...i also know that there is a great chance that ill find more issues the further in i go...piston and rings...grrrrrr

How long does it last for?

Were do you buy this champion?

I enjoyed it, thanks man

Did you lose the installation tool?

Great video ... Thanks

Thanks for doing this video, it helped a ton!
