 ===== Problem with the Keyster valve seat =====
-After overhauling the carburetors with the Keyster kit, I had a problem with the float valve seat. Even though I had adjusted the float level according to the manual (9.2 mm), after driving for a few kilometers, the fuel began dripping from the carburetor vent tube. Evidently the valve wasn't closing, and the float chamber was overfilling.

Evidently the valve wasn't closing, and **the float chamber was overfilling**.
-To confirm that the fuel level was the problem, I connected two clear rubber hoses to the carburetor drains. The hoses were then bent upward, above the fuel cap. By loosening the **drain screw**, you can see the fuel level in the hose, which will be equal to the level in the float chamber. After a few kilometers of driving, I noticed that the level in one of the two carburetors had risen several centimeters and was now reaching the breather pipe.
