Is it on a 12a ? If so have you advanced the dizzy to the advanced position ? Been Running like that for some time. Got told it was just something to help emissions and fuel usage.

From mine it was advanced all the time on the dizzy. I\'m not sure by how much but it is set into the advanced position on the dizzy. It will use more fuel on tickover !
