Mechanic in a Bottle Fuel System Fix All Fuel Additive, 4 oz bottle

This is my “go to” response when experiencing fuel problems returning small gas equipment to service after setting. Very effective in removing “lacquer” build up and oil fouling in carburetors by just adding to the fuel or in sever cases, by draining the fuel and filling the fuel system with MIB and letting set overnight.

In my personal experience if you can get any gas through the carb a 50/50 mix with gas will soon have it running at it's full range. I've even used starting fluid to keep it running long enough to pull a vacuum. Of course the use of starting fluid is at your own risk due the lack of cylinder lubrication. Good stuff.

My pusher mower wouldn't start. I drained the gas and took the bulb off the carburetor and filled it with Mechanic in a Bottle and put it back on the carburetor and let sit a couple days. I removed the bulb and poured out the Mechanic in a Bottle. Replaced the bulb and put fresh gas in the mower, it started right up.

Complete snake oil. Took all the gas out of generator and put in the 4 0unces and left overnight. Took out the mechanic the next morning and put in fresh gas. The generator still surged, just as before. Finally took the carb off and cleaned out the clogged jets and it now runs perfect. This stuff is complete junk. Avoid and don't waste your money

Whatever magic is in this Mechanic in a Bottle stuff, it's kept our old mower going for years. Other additives don't seem to help. About a teaspoon of this stuff and it starts up without tons of pulling. I won't be without it and try to keep a spare bottle ready at all times.

Works!! This definitely worked for me with an older mower that was struggling to start. It took a few times for the results to show but it definitely made a difference!

My husband uses this in all gas items lawn mower motorcycles backhoe anything and everything it really does work to unclog has itemes

A very effective cleaner. I have used in several older mowers that would not start. sometimes can take a day or two to dissolve blockages .

I've been using this for yearsand it works great.if you have a ruff running or small engine unit. Try this before you bring unit to shop.

I know of a few people who have used this product in the past but I was hesitant to use it until I seen a small engine mechanic that I follow on line use it and it worked better than expected.
