I have recently been renovating a Ransomes Marquis Mk4A which had been resting for over twenty years in a dry barn. It all runs perfectly now but I just can not loosen the clutch to make the adjustment to fit the new cylinder drive chain I have bought. The last chain must have been very slack as the clutch has been set so far back to tension it.
I have made a couple of pin spanners but neither was strong enough to loosen the nut. It has been soaked in Plus Gas, any ideas or just make a super strength pin spanner? I did one of these a couple of years ago and had no problem at all with this adjustment.
