Re: carb and throttle
How much is, "A slight tilt" ? If you're only talking about a few degrees off center then you'll be okay but don't exceed about 10 degrees. Rotate the carb just enough to allow the cable to clear whatever obstruction you have. I slight tilt is tolerable; it has to be or you couldn't ride around curves without the engine being effected. Just keep in mind that there is a float inside the carb's bowl that needs to be somewhere in the ballpark of level to function correctly.
