Funny thing. I realised I was over-revving on every gear change (like a newbie) and carefully lifted more than usual to compensate, moved the foot well carpet, etc, but same thing happened. Was it in my mind? Just when I convinced myself that I wasn't going barmy I decided to Google and found out about sticky accelerator. I have some carb cleaner ready to spray but is there a pictorial showing what I need to disconnect and spray/clean? I'm a visual person.
