Hello everyone been awhile since I’ve been on here. but I have came to you the community for help with the 02 660 griz again. I need to do a helicoil repair on it and I have no idea where to begin or what to do or what to buy. I just replaced my battery last weeked and got it to turn over and running and let it run for about 30 minutes and as I was putting it back in the garage and next thing I know I hear a pop and ting and the sparkplug was laying on the floor. Trying to see what my options are if you guys or gals can help that would be great just let me know.

And as always stay safe and have fun
