Testimony

"Your MIB has saved my 7 year old Honda mower which was very difficult to start for the past two years.  It now runs and starts "better" than new.  Your product does what you say.  I am now a believer in your products and realize the deteriorating effects of ethanol in gasoline. Thank you for saving me from much expense and agony."

Mechanic In A Bottle (MIB) Mechanic's Instructions

Download & Print

MIB is designed to clean the fuel system without removing the carburetor. By not disturbing the original factory seals or introducing other contaminants inadvertently, this will not only speed up repair time, it will also reduce further technical complications. If there is physical damage to fuel system components such as torn / rotted rubber components or scale (white rust) from phase separated fuel the fuel system will have to be serviced further.

UP TO 80% OF ENGINE REPAIRS START WITH BAD GAS 
FIX these problems with Mechanic In A Bottle & 
PREVENT future problems with Ethanol Shield!

USE MIB THE FIRST TIME YOU START YOUR EQUIPMENT EVERY SEASON FOR EASY STARTING AND TOP PERFORMANCE!

FIRST Step is SAFETY: Disconnect the spark plug lead from the spark plug until you are ready to start the engine!

IMPORTANT: You must get the MIB into the carburetor for it to clean the fuel system components and rejuvenate the plastic and rubber components from the adverse effects of the ethanol blended gasoline.

Step 1:

4 Cycle Primer Bulb (click for details)

Determine if the fuel is fresh, stale or marginal with a Mechanic In a Bottle gasoline Quality Test Swab. If you do not have one then try to determine if the fuel is marginal or bad (stale) by smelling the fuel briefly for a sour scent. Keep in mind ethanol has an overpowering scent and will mask the sour decaying fuel. If the test results indicate or you assume it is marginal then proceed to Step 2.

If the fuel is stale or you have 2 Cycle Equipment proceed to Step 3.

Step 2:

4 cycle choke (click for details)

  1. Add at a rate of 2oz MIB to 1 gallon of fuel the MIB directly to the tank with marginal fuel. Agitate the equipment a few times to ensure the MIB is distributed throughout the fuel. Top off with fresh gasoline if desired.


    Choke Style Starting: Place the choke in the ON position and rotate the engine 6-8 times.

    Primer Style Starting: Depress the primer bulb 6-8 times.

  2. Now let stand overnight or for at least 6-8 Hours (results have been seen in as little as 15 minutes).

  3. Reattach the spark plug boot and attempt to start the engine.

  4. If engine starts and runs properly continue to run an additional gallon of fuel with MIB added at the rate of 2oz to 1 gallon of fuel to deep clean the system.

  5. Use Ethanol Shield with future gasoline purchases and follow the directions on the label to protect your fuel system and preserve the fuel.

Step 3:

      Primer Style Starting: Depress the primer bulb 6-8 times on machines equipped with primers and prime the MIB into the carburetor.

      Choke Style Starting: On machines with chokes you will need to loosen the bowl drain on the bottom of the carburetor (if equipped) to allow the MIB to enter the carburetor bowl, use shallow bowl under the carburetor to catch excess MIB and tighten the bowl nut once you see MIB coming out.

    2. Be sure the spark plug boot is removed. Place the choke if equipped in the ON position then pull the engine over 2 times and let stand for 1 hour, if you suspect a severely contaminated fuel system then let it stand longer or even overnight. Proceed to Step 4

Step 4:

  1. 2 Cycle Equipment:
    Leave the MIB in the fuel system and add fresh gasoline mixed with 2-cycle oil to the fuel tank and cycle the primer bulb 8-10 times to flush the carburetor and mix the MIB thoroughly.

    4 Cycle Equipment:
    Leave the MIB in the fuel system and add fresh gasoline to the fuel tank and prime it into the carburetor. Note on some machines you may need to loosen the bowl drain on the bottom of the carburetor to allow the gas to enter the carburetor bowl. Use shallow bowl to catch the MIB / gas coming out. Once you see gasoline coming out tighten the bowl drain nut.

    CAUTION: Check for fuel leaks and clean up any spilled gasoline allowing sufficient time to let dry before attempting to start the engine.

  2. Reattach the spark plug boot and attempt to start the engine.

  3. If engine starts and runs properly continue to run an additional gallon of fuel with MIB added at the rate of 2oz to 1 Gallon of fuel to deep clean the system.
