As for the plugs, I feel like I should have them replaced in order to see what is happening inside of the cylinder (burning plugs or whatever). So will any plug work from that list that you have provided?
Also, on the strap - it's about 1/8" thick. I don't think you'll be cutting it with snips unless your hands are a lot stronger than mine. A hacksaw will eat right through it, though. You want a little thickness to it so the clamp part grabs it firmly.
