It was way, way overpriced. The post was very misleading, indicating that it was more professional as in a higher concentrate & it wasn’t. I feel totally cheated. & the bottle was damaged as well.

I was going to buy a new carburetor for my Honda Generator, but the Dealer told me to give Mechanic In A Bottle a try.I laughed because I thought he was kidding, but he was serious. He told me that he would order the $70 carburetor but insisted that I give a small $5 bottle a try and if it worked, he told me to just give him a call and he would cancel the carburetor order. IT WORKEDMy Dad bought the new EB 5000 Honda Generator in the early/mid 90's. He took the generator home, filled it with gas, fired it up, plugged in a lamp to make sure it worked, shut it off and put it in the back of his shop and there it sat until 2020, so the gas sat in the carb 25 or more years, was brown and smelled more like solvent than gas. When I got the generator I drained the gas and filled it with new gas. It fired on the 3rd pull, but it ran so bad it just spun around in circles in the driveway. I removed the carb and cleaned it with a can of carb cleaner and blew it out with my compressor, but it still ran terrible.After buying the bottle of Mechanic In a Bottle I filled the carb with MIAB and dumped the rest in the fuel tank and let it sit for an hour. After it sat for an hour I fired up the generator and it still ran rough and still spun in circles in the driveway, but after 5 minutes it started to run better and after 15 - 20 minutes it purred like a kitten and has run great ever since.I now run Mechanic In A Bottle in all of my generators, chainsaws, weed eaters, blowers and mowers and even after setting for over a year they all fire right up and run as good as they did the last time I used them.

Got an outboard that had trash in carb running like brand new. Pressure washer running great and a 4 wheeler that was on verge of a carb job. Highly recommend. Buy it and it will save you money and time. Better than sea foam by miles.

I own a lot of power equipment and atvs in the mountains and often they sit for month without starting. I add this CNN product to my gas cans so it in all of my engine tanks. I e arely have trouble starting any more. And they run quiter and smoother. I put it in my high mileage work trucks as well. Highly recommend. Please keep the gallon option available

This stuff works great. Inject in fuel line intake and let sit......ald if needed let sit. On my riding zero turn ,I was bogging down on high grass, so had to slow down, after treatment I can go full speed ahead!
