Hi
A good way of checking if timing is roughly right is to remove the plugs, connect one to a lead and hold/connect to earth, spin the engine on the starter with the ignition on, with a finger over the associated plug hole, or a compression test gauge. You may need three hands or an assistant! Take care not to get a shock or anything tangled as the engine turns over. If you get compression and the plug is sparking at the same time the ignition is roughly right. Normally just checks on number 1 cylinder are required unless the leads are wrongly connected.
Changing leads around works, but can be very confusing later on if you don't correct.
