It works, but then I just did it for the first time. When you go to the auto parts store the guy at the counter will say "ahhhh the magic" or something like that, knowing you too have found a secret and will nod in approval. Can't hurt to try it out, honest, what's six bucks? I have put it in old motorcycles and to store small engines over the winter or my snow blower in the summer, and all my engines seem to run like a champ. Give it a shot, really, this takes no time at all, the booster line is easy to get to and remove, once it sips up the sauce, you are basically done.
