[QUOTE="SRAD97750, post: 130749, member: 425"] This lean bog is caused by the massive volume of air versus the gravity fighting the fuel through the main jet. The air wins which can stall the engine. It should be minimal with a clean, properly set up carburetor. But still noticable if you are quick with the throttle. This is the reason they invented Accelerator pumps on carburetors. An accelerator pump us activated by throttle cable directly, when you grab it quickly, a stream of atomized fuel is SQUIRTED into the intake, which solves the lean situation. -BIG DAN:thumb: [/QUOTE]
