Carburetor settings for a 1978 suzuki gs550. Mainly how many turns out should the screw on the bottom be out?

The air/fuel mixture screw on a Suzuki VS800 Intruder is typically located on the carburetor. To adjust the air/fuel mixture, you'll need to locate the carburetor and look for a small screw that can be turned.
Keep in mind that the exact location of the screw may vary slightly depending on the model year and specific carburetor version on your VS800 Intruder. Generally, it is located on the bottom or side of the carburetor.
Here are the general steps to locate and adjust the air/fuel mixture screw:
1. Locate the Carburetor: The carburetor is usually positioned on the side or underside of the engine. Follow the intake manifold or air filter housing to find the carburetor.
2. Identify the Air/Fuel Screw: Look for a small screw on the carburetor. This screw is typically flat-headed and may be recessed. It is often located near the bottom of the carburetor.
3.Adjustment: With the engine running at idle, use a screwdriver to turn the air/fuel mixture screw. Turning it clockwise (in) usually leans out the mixture, while turning it counterclockwise (out) enriches the mixture.
4. Listen to the Engine: As you make adjustments, listen to the engine's sound. The goal is to find the point where the engine runs smoothly and the idle is stable.
5. Fine-Tune: Make small adjustments and give the engine a moment to respond before making further changes. It's a process of trial and error to find the optimal setting.
6. Check the Owner's Manual: Refer to your motorcycle's owner's manual for specific guidance on the location and adjustment of the air/fuel mixture screw. The manual will provide information tailored to your bike's make and model.
If you're uncomfortable making these adjustments yourself or if you're unsure about the location of the screw, it's advisable to consult a professional mechanic or refer to the specific service manual for your Suzuki VS800 Intruder.

1 1/4 turn is the correct setting. That could be the problem. Or the carb is gummed up inside. sticky floats or a leaky intake gasket could do this as well.

see your parts dept at any suzuki shop.tell them what you want.(they will have pictures to compare and order)

sounds like its running to rich, check your air filter is clean, set your carb mixture ,
turn the screws in untill they bottom out ,but dont turn to hard !(they have a fine needle point end and are easy to break leaving the broken point inside the carb making adjustment impossible )back all four screws out 1.5 turns and start from there.run the bike and adjust from there to rich turn out to lean ( weak turn in )

www.thegsresources.com a good web site for these bikes.

good luck

You will have two lines coming from the petcock on the bottom of the gas tank. the small one goes to the front of the number one carb, and the larger one plugs onto the fuel rail in the middle of the 4 carbs on the back. The lines that run between the 1 and 2 carbs and the 3and 4 carbs are just overflow lines, so they don't hook on anywhere else.
