Just picked up a Korado. Ran wonderfully. Then I took it home. Degreased the engine. And later gave it a rinse with the garden hose. Did I dislodge something? I noticed a tube coming from under the Bing 18 carb that leads to nowhere. Also noticed a tiny hole between the two intake bolt holes. Does it feed into here? I'm wondering if fuel is drawn past half throttle by suction of the cylinder? Not too sure. My first Korado. My Maxi is a bit different. It basically bogs out or stall out under higher throttle. All internals of card are tip top, and again, it ran great, until I rinsed the engine. I was careful not to get any water into the air cleaner area or cylinder. I'm puzzled.
