[QUOTE="turbotodd, post: 467171, member: 7376"] Usually if the idle jet is restricted or plugged, it will not idle properly, if at all, and that applies to almost all of the Yamaha's (at least all the ones I've worked with). A bog is "usually" a function of an accelerator pump issue. That could be due to a restricted nozzle, restriction in the bowl, check valve misplaced in the bowl (usually apparent by a loose snap ring), plunger stuck, or a leaky bowl gasket. The nozzle is not replaceable. The orifice in the bowl is also not replaceable so if it's plugged, or the nozzle is plugged or restricted, you have to replace the carburetor or the bowl, or both depending on what's restricted. Does it start easy when cold? How is the oil level? Those should be about 1/2 to 3/4 way to the high mark on the dipstick. If over-full, it can affect how it runs. [/QUOTE]
