Ok Gadge or Grumpy, or anyone even that's got one of these older greenfields. When selecting forwards or reverse, mainly reverse on mine, it's very clunky. So basically it'll sit there for a bit with full pressure on the pedal and do nothing, all of a sudden wham it hits reverse and off you go.
I'm assuming without looking it's just a sticky selector on the clutch shaft. Best remedy? Graphite grease?! The square shaft was very clean, no burrs or anything when it was reassembled.
