Reviews

Mechanic In A Bottle is rated 5.0 out of 5 by 10.
Rated 5 out of 5 by from Best stuff ever! Had a brand new push mower. It was only run twice last fall. I ran the gas out and parked it for the winter. Went to mow the lawn yesterday and it wouldn’t start. No gas getting to the carb. Bought the MIB and squirted a bit directly into the carb and put a bit in the tank. Waited about 30 minutes and it fired right up!

Rated 5 out of 5 by from Works just as advertised I have two generators. one's a Honda EU 2000, the other a 4000 W Champoin. Neither had ben used in 3-5 years. When tried, they would sputter but not run with a half tank of new and old fuel. I found MIB at a Tractor supply here in Presacott, AZ, and poured bottle in eash one. I let them sit overnight. In the morning, the both started almost immediately, and are fine now. highly recommended.

Rated 5 out of 5 by from Fixed carb instead of rebuild - very cheap fix! My neighbor had neglected their lawn tractor and asked me to help. This is what I did: The carb was just pouring gas. I removed the anti backfire solenoid which seemed to be sticking and got it moving. I drained all the gas and poured in 4 oz of MIB, (which seems to be a blend of different types of alcohol) cranked the engine then let it set for about 5 hrs. In that time the carb stopped dripping. I removed the rest of the MIB and put in a gallon of fresh gas. Two squirts of starting fluid and so far its been running like a champ! Before I ever rebuild a carburetor I will try this stuff first!

How much do you use for a Chevy V8 motor 350

Asked by: David Brown
We normally recommend 1 oz to 10 gallons for normal automotive use. You can not over treat with the product, so a stronger mixture is ok.
