my old paloma DASL 39.6mm stroke in 1960 the recommended timing setting was 4mm BTDC
should i set this to 2mm with the state of petrol and some tiny improvements to the motors breathing?
the spark plug hole enters the head in at an angle and is to one side.
will i ever see decent power with the spark plug like this?
i suppose this affects the ignition timing and maybe why it is so advanced? am i best converting it to centrally located? or could i even fit another plug hole at the other side?
