That's a very good question. We messed with different settings. One tilted forward, one level, and believe it or not, it didn't make much if any difference. I like to have mine level when engine is in your car, mainly just for setting bowl levels. Alot of engines are tilted back to align the driveshaft to the rearend. On that application I would probably use the tilted intake, other than that I would run the intake that is level....

10 years ago I turned a dragster over on it top. It slid upside down and facing the wrong way from the finish line until it came to a rest. I was lucky that the front wheels were touching the ground, allowing me to keep the dragster in the middle of the track until it came to a rest. It took out a slick, knocked the scoop off and scratched a header. The reason I told this story is when I got to the other end the engine was still running. In my state of daze I even racked the engine back before I killed it like I would any other time. The carb works on vacuum more so than gravity. A stutter is probably a lean problem, IMO alittle tilt of the carb wouldn't cause it, unless you have a bowl set to high.....

Some of the wedge spacers are suppose to have the carb level under hard acceleration. In theory it's to keep the fuel flow even to all the cylinders.
And yes a stumble comes from the carb being to lean.
