Quicksilver 858080Q03 Power Tune Internal Engine Cleaner for 2-Stroke, 4-Stroke and Fuel-Injected Gas Engines - 12 Oz.

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.

I love this product. Works great. Highly recommend it

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!

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!

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.

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.

I did an overhaul on our 87 Evinrude 40hp outboard this spring. New plugs, wires, coils, power pack, timer, etc. Rebuilt and re-sinked the carbs. Still ran a little rough (for a 2-stroke). Figured I'd give this cleaner a whirl. I did like the directions said. Ran the engine till it was up to temp, then started spraying this in the carbs. Just before the can was empty, I started spraying heavy until it stalled. Let it set for 24 hrs, then fired it back up. It sputtered a bit, as expected, then once it warmed up it smoothed out. Let it run for about 5 minutes with the earmuffs on in our lawn. When I shut it off, there was a 1'x2' area under the prop that was black. Seems like it burned out all the old oil and carbon build up. Engine now seems to start and run a lot better. Would definitively recommend giving this a try if you're having similar issues. I'll probably run this through each spring now (as advertised) to stay ahead of it.

My Honda generator in our RV would not start. Determined I had a stuck carb needle&seat. Watched a YouTube video with the idea to spray this into the float bowl VENT. Made a little hose adapter to the sprayer straw and blew it in. Could see thru my clear hose its a foam, so sprayed and waited for foam to settle. Cracked open the float bowl drain and checked all drain hoses clear (one wasn't). Loaded the float up good and let it set 30-45 minutes. Crossed my fingers and cranked...after a couple starter cranks it started!! Hallelujah! Smoked a little for a couple minutes (old crap burning off) and cleared up. I must have saved a small fortune NOT going to the RV or generator dealer and likely the whole year of RV travel. So thrilled! GREAT $10 fix!
