Hi I was cleaning my Carburetors out, as I was having trouble trying to start engine. I noticed the 3rd carb from the left has a little hole that seems to be plugged with metal, but none of the other Carburetors have this. Is it normal, not sure if you can upload photos?
It is called a 'blanking plug' and covers the idle mixture screw and is put there to stop owners from fiddling with the idle mixture screw. Not sure why it is only on one.
OK thanks Andrew, should they all have that plug? I don't seem to have a photo icon, to be able to upload a photo!!OK thanks Andrew, should they all have that plug? I don't seem to have a photo icon, to be able to upload a photo!!
Ah, that isn't the blanking plug I was thinking of. The Idle Mixture blanking plug is on the outside. No idea what that is.Ah, that isn't the blanking plug I was thinking of. The Idle Mixture blanking plug is on the outside. No idea what that is.

The baseline throttle slide height for a Suzuki GS750 motorcycle should be set so that the slides are fully closed when the throttle grip is in the closed position. This means that when you twist the grip fully counterclockwise to the stop, the slides should be flush with the carburetor body.
To adjust the throttle slide height, you will need to remove the carburetors from the bike and use a feeler gauge to measure the gap between the bottom of the slide and the carburetor body.
It is important to make sure the throttle cables are properly adjusted before setting the throttle slide height. The throttle cables should be adjusted so that the throttle grip moves the slides smoothly and the grip is in the closed position when the slides are fully closed.
It is also important to keep in mind that the carburetors on a Suzuki GS750 motorcycle should be synchronized after adjusting the throttle slide height. This ensures that all carburetors open and close at the same time and at the same rate, which is necessary for proper engine performance.
Please note that this is a general explanation and the specific process may vary depending on the year or model of your Suzuki GS750 motorcycle. It's recommended to consult the service manual for your specific bike for detailed instructions on adjusting the throttle slide height and synchronizing the carburetors.
The Suzuki F6, F6A, 6 valve, and 12 valve engines do not necessarily use the same carburetor. The carburetor used on a particular engine depends on factors such as the engine's displacement, number of cylinders, and year of manufacture.
For example, the Suzuki F6A engine, which was used in various Suzuki vehicles such as the Suzuki Carry and Suzuki Jimny, has several different carburetor options depending on the model year and vehicle application. Some of the carburetors used on the F6A engine include the Hitachi DM14, DM20, and DM24 carburetors, as well as the Suzuki F5A and F8B carburetors.
Similarly, the Suzuki F6 engine, which was used in the Suzuki Cappuccino sports car, also has a specific carburetor designed for its engine configuration.
Therefore, it's important to confirm the exact engine model and year of manufacture, as well as the vehicle application, to determine the correct carburetor for a particular engine.
I answered this yesterday. It is shown on the top of the diagram. 4th image ion the Amazon advert, small brass screw. Make sure you have got the cable adjuster too tight as that will cause a high idle.
Theres a set on ebay right now bud http://cgi.ebay.com/ebaymotors/77-SUZUKI-GS-750-GS750-GOOD-SET-OF-CARBURETORS-CARBS_W0QQcmdZViewItemQQhashZitem3a59c70406QQitemZ250614318086QQptZMotorcyclesQ5fPartsQ5fAccessories
It could be a clogged jet on your carburetor, it could also be varnishing in the float bowl possibly making the float stick. Try cleaning out the carb with carb cleaner and blowing the jets with air, not too much air pressure.
Sounds like water in the gas.
ALWAYS have a fire extinguisher on hand when working on carburetors. For each carb > Drain the carburetor. There should be a screw on the lower side or bottom of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.
Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Put the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road. Please rate this solution. Thanks!
