I'm Sat Waiting On Postman Pat

Something else I need to have a squint at is the possibility of using the piston I've already altered but extending the stroke by moving the Rekord pin holes backwards in the back block.
This would increase the stroke and also give a setback trigger, but I have a feeling there's not enough room in the block to do it.

All the best Mick

Wow! Now that is extreme thinking out of the box. Guessing, like you say, that there may not be enough room to allow this, but you never know.........
