Hi,
Hope you can help me on this
My 280 has started to hunt when warmed up only when I am going slow it is lunging forward and this makes it difficult to ride at low revs
It revs well and is fine at higher revs
I have cleaned the carb blown out the jets and replaced the plug but it starts off great but as it warmed up it starts playing up

Thanks
Alb
