Well, difficult to engage anyway. 30 miles from home stuck in 2nd and eventually with jiggling of the lever managed to get all gears and it took a few attempts each time but once the lever was moving the box went up and down ok. This is what I found today, the main return spring not completely broken but almost. I completed the break removing it. I was amazed I was able to select gears at all. So unreliable these 45 year old parts!! :wink:
