When I went out for a run a week ago the engine suffered from rough running under load after about four or five miles. The petrol was probably a year old, and the distributor points looked past their best so I've drained the tank and filled with fresh fuel, fitted new plugs and points, taken it for a run today... after four or five miles it started misfiring, not like last weekend, but only above about 3000 revs (25mph in second, 40+ in top); it would take full throttle up to these speeds, then the misfire.
