right then i did that and everything inside it is like new well not new but as u described the brushes have loads of meat left and are the same colour all the way along them and bit that they touch is nice and shiny
i think it could be my gearing that is to high
im thinking that if there nto much bottom end and not much topend then it may be to highly geared so the motor cant reach its full rpm
im gunna try a different pinion on it tomoz
ill report back
cheers
