Worked Great
Can't believe all the carbon that came out. Ordered 2 more cans for other equipment. Probably will order more. Does make a difference in the motors running better.

Works good.
I dont have much to compare this to, as it was the first time cleaning a carberator for me.With that being said, it seemed to work well. I followed the directions, and it did clear quite a bit of smoke as the directions stated would happen. Engine runs great now!

Cleans nasty fuel injectors.
I used this to clean the original fuel injectors in my '03 Silverado. It runs better now than it has for a long time and gets better mileage too. And yes, it works similar wonders on my boat which is pulled by that same truck!

Amazing Product
I used this on my 79 Mercury 80hp and it improved compression, performance and the starting time of my motor. If you have an older outboard this is a must have. You won't be disappointed.

Works!
Took the advice to try this product tho help clean out my old motor and it worked. If you’re not a gearhead try this before dismantling your carburetor.
