Even though my 280 110 engine preforms well, with good compression ,and plenty of Ignition advance, I feel the lack of low down Torque.
Even with a 1st gear start 4 speed Auto I find I have to manually shift back a gear to often. The camshaft timing is 2% retarded on the exhaust and 1% on the inlet. Web information says advance the timing to give more low down Torque. But my experience with a 1913 Rudge Motor Cycle was the opposite.
Factory setting was 10% "A"TDC, inlet, ( steam engine timing ) very late I thought , so I set it ,via a it's fine adjustment facility, to 10% BTDC. Lost all it's low down Torque but gained a lot at higher Revs. A compromise was 5% ATDC.
Which is correct for low down Torque , advance or retard the Camshaft ?????
