Review on ⚙️ Time-Sert M14x1.25 Spark Plug Thread Repair Kit - Find p/n 4412-321 Online by Dustin Citizen

Let me start by saying that I rarely try to write reviews, good or bad. This product however. Worth the time! I'm an experienced DIYer who used the Time-Sert tool kit to repair damaged spark plug holes on a set of vintage aluminum tractor heads. Worked like a champ! As easy as following the instructions. I did 2 repairs in 1 hour, tightened the compression and ran the tractor a few seconds later. Of course, aluminum is easy to machine, but I have no doubt that this tool kit will give almost the same results on iron heads. The set is packed in a compact, robust plastic case. The instrument is first class and well made. This particular kit also included 5 inserts that were easy to refill. The only thing I liked was the extremely simple, bordering on sadness, "insert" command. Not even on the whole page, but the images appear to be copies of copies of copies - verging on faded and poor resolution. Easy enough to understand but for the price of the kit I think they could do a little more with the instructions. All in all very recommendable!
