08 beta rev 125 fouling plugs

Recommended Posts

I have a 08 Beta 125. Runs perfect... untill you put it nose down or nose up. It then changes idle and fouls a plug. Within a matter of seconds. Any ideas?

Wasn't the float. 

I adjusted it to spec and it still fouled.

I think it has something to do with there being a breather hole in the float chamber, which lets neat fuel into the engine, when the angle of the carb is tilted forwards.   Maybe this could be modified, or blocked up, but the float chamber still needs to be ventilated somehow.

Take a pic of the carb as it sits. I am betting a vent hose issue.
