A friend has a ms311 that spit the spark plug out and stripped the threads out. Can the hole have a helicoil put in it? Has anyone done this before and is it much trouble? Thanks
For a one time deal you have gone the best route, the kits are expensive and overkill if one is not doing these repairs often. I cringe to think of how much I have tied up in kits and install tools.
I bought the Save A Thread kit and did four so far. Had to buy another pack of shortys.[emoji108]
Now on loan to another member. [emoji106]
I have the kit and have put at least five in the last couple of years. I have had good luck with all of them, but one. The main thing is to set the insert after it is in with the expanding tool and to either put Yamabond or JB weld on the threads gas/air pressure can come through the threads and lower compression. The one I had problems with was a Remington 5520 as the cylinder was made in Taiwan and the threads were so soft when trying to set the insert it stripped them again. A POS
