I have been using this for years. We call it carb rebuild in a bottle, if you have any carb gunked up, run just a little through it, let set over night. Test it, get a jet n soak it 50/50 with gas. In the morning you be looking at a new jet. Ran this through a 4 cyybike that was sitting, mixed up a batch with new fuel. Let it idle about 10-15 minutes, you could it slowly hear it clearing up from a rough to smooth idle. Unfortunately the price has about doubled, so I use much less of it now.
