I've noticed something weird in the design of the Huasheng engines. It looks like the engine was designed to allow blowback from the engine directly to the air filter. There's a fuel line that runs between the two bypassing the carb. This probably improves performance during operation and the saturated sponge-like air filter likely helps catch particles and subsequently helps ensure the air filter remains clean but this brings about one small problem....
The air filter leaks gasoline when the engine isn't running. It's only a small amount of gasoline that leaks from it when parked but it seems like a weird design choice.
Can someone explain to me if i'm understanding this design choice correctly? Or if there's another reason it was done like this?
