The **factory settings** are likely to be for a **very lean mixture** at idle, which is also why the cut-off valve is needed. This setup is required to meet stringent pollution regulations. It may be that the best idle performance is achieved with a richer mixture (pilot screw turned out more than two turns). A richer idle also reduces the possibility of afterburn (exhaust popping) when the throttle is released. | The **factory settings** are likely to be for a **very lean mixture** at idle, which is also why the cut-off valve is needed.

+ | In the following photos you can see how the fuel line and the breather tube are positioned around the carburetors (the lower end of the breather pipe should be inserted into the binder, together with the fuel pipe). This is how I found them in my 1991 Revere, but I found other models having the breather tube going to the right side, in a mirror-like way. | ||
