Do you need a carb sync on a multicylinder?
What you need is a good sync, a carb sync that is. What’s that? On multicylinder bikes with separate carburetors (or fuel-injection throttle bodies), all carbs need to be doing their fair share and operating in tight lockstep with one another.
What’s the best way to synchronize a carburettor?
Loosen or tighten those screws, bit by bit, opening up the throttle in between, until all the needles on the gauges rise and fall simultaneously, in perfect harmony. This does take its time, and can be a bit frustrating, not to mention noisy.
What are the symptoms of a too rich carburetor?
Too Rich. When a vehicle is running rich, the fuel-to-air ratio is off because the carburetor is delivering too much gasoline. Typical symptoms of a rich mixture are: Poor fuel economy. Sluggish acceleration. Choke not needed from cold starts. Sooty or black spark plugs.
When to know if your carburetor is running lean?
Before attempting to fix a carburetor problem on your motorcycle, you need to come up with the correct diagnosis. When a carburetor is running lean, the fuel-to-air ratio is off because the carburetor is delivering too much air. Typical symptoms of a lean mixture are:
Is the choke spring part of the carburetor?
Spring: The choke spring can be either integral (a part of the carburetor), such as the design used on the later Rochester Quadrajet, or divorced (not attached to the carburetor), which was common on Chrysler products. When divorced, a linkage connects the spring to the choke plate.

What should I do if my choke does not work?
If the engine does not start when cranked over for a few seconds, release the key and press the accelerator to the floor one more time to evoke an additional accelerator pump shot. Most automatic chokes have a “clear flood” mode or “unloader” that is carburetor-linkage operated.
