Gas and Ignition levers on steering wheel

[Tony Griffiths]

From a middle setting on the control where the car pulls well - but without the death rumble from the cranks - to what sounds like more power but isn't, is only perhaps 20 degrees on the hand control. The only way of finding the best setting is to experiment on a flat road where you can see if an extra 1 mph can be persuaded out of it - and mark that position.  If you have electronic ignition, it's surprising how much retard it will take to get a soft-sounding motor and yet reasonable power.
