Re 40/50 HP Chassis - Exhaust Choke Valve Spring E.22678.
With reference to your remarks re the above, we suggest you try out links similar to E.22679, but 2.000 and 2.500 centres respectively.
The longer link gives the 3.750 centres (half open) that you require, but in our opinion means too large a reduction in spring loading.
