As Kevin mentioned, genuine Heli-Coil kits ARE expensive, but if you shop ebay, you can generally find them fairly close to the price Kevin quoted for the Amazon kit.
There used to be a cliche: "You get what you pay for".
Sometime ago, I paraphrased that cliche as follows: "You generally DON'T get what you don't pay for".
Over the last 50 years, I have installed hundreds of genuine Heli-Coils, with NEVER an issue.
I did test some of the less expensive knock-offs and then threw away the castings.
You get ONE opportunity to correctly fix the stripped threads, and then you get to replace the carburetor.
Which is the most expensive; the Heli-Coil kit or a carburetor ?
