• Adjust the screws equally until you achieve the desired idle speed
• Turning the screws clockwise will decrease idle speed, while turning them counterclockwise will increase it
• Once you’ve achieved the desired idle speed, turn off the engine and double-check that all connections are tight before restarting it

Johnson V4 Idle Adjustment

If you have a Johnson outboard motor, you may need to adjust the idle at some point. This is not a difficult task, but it is important to do it correctly. Here are the steps you need to take to adjust the idle on your Johnson V4 outboard motor:

1. Locate the idle adjustment screw on the side of the carburetor. This is usually marked with an “I” or a “+” sign. 2. Use a Phillips head screwdriver to turn the adjustment screw clockwise or counterclockwise, depending on which way you need to adjust the idle.

3. Turn the screw until the engine speed reaches its desired RPM level. For most engines, this will be between 750 and 1000 RPM. 4. Once you have adjusting the idle, tighten down the locknut that holds the adjustment screw in place so that it does not move accidentally.

Johnson 40 Hp Outboard Idle Adjustment

If you have a Johnson 40 hp outboard engine, you may need to adjust the idle speed from time to time. Theidle speed is the speed at which the engine runs when it is not under load. It is important to keep the idle speed adjusted properly, because if it is too low, the engine may stall and if it is too high, it can cause damage to the engine.

To adjust the idle speed on a Johnson 40 hp outboard engine, first locate the idle mixture screw on the carburetor. This screw regulates the amount of fuel that goes into the engine at idle. Turn the screw clockwise to lean out the mixture and counterclockwise to richen it.

Next, locate the throttle stop screw on the throttle body and turn it clockwise to increase the idle speed or counterclockwise to decrease it. It is important to take your time when adjusting these screws and make small adjustments until you get the desired result. Remember that too much of either adjustment can cause problems, so take it slow and be careful!
