Is your ride bogging out over bumps, or dying when coming to a stop? Adjusting the float level may fix that. Our model in these picture is PD30J, however, this information applies to all GY6 carburetors.
1. Flip over your carburetor
The float bowl should be oriented topside.
2. Take note of how float internals are arranged
So you’ll remember how it goes back together.
3. Use a pointed tool to push out the float pin
With the pin sticking out on one side, you can more easily grab and remove it.
4. Free and remove the float
5. Make adjustments at the tab
The most common float-related problem is that the float level is set too high from the factory. This can cause bogging over bumpy terrain and dying out when coming to a stop.
To lower the float level: Carefully bend the tab downwards slightly.
To raise the float level: Carefully bend the tab upwards slightly.
Important! Be sure to bend the tab only slightly. Small changes in the tab angle will equal out to big changes in the overall float level once reassembled. You may have to go through this process a few times to get the optimal level and riding performance.
Important! During adjustments, the float should be oriented the same way as it came out of the carburetor.
