I saw it at my local shop. It's called powervalve cleaner and it's in a bottle. I think it said to put 1-2 ounces in with 5 gallons of gas. Works on 2 or 4 strokes. If 4 strokes have powervalves? (I think I'm going to be embarassed on that one) I want to know if I can always run it to keep it clean, or if I can only run it when it needs cleaning.
1. I don't know if it needs cleaned. 2. I don't know where it is. 3. It's not wasting money if it works. 4. I shouldn't mess with things that I would most likely break than fix. 5. I just want to know if I can consistently run some through.
