We see a lot of CU engines which have had a fair bit of time and money thrown at them to get them running and looking lovely… then they’re often let down by a bodge on the end of the cable where it attaches to the linkage.
The reason is that this bearing pin hasn’t been available for a long time.
In the past we’ve had to make them in the workshop when the bodges have failed… time consuming and expensive. So we now keep these on the shelf.
