A15 with t/bodies and ecu--been on the dyno etc. I checked the dissy and the set-up looks wrong[it's hall type].this chap at the dyno advanced the dissy so far it lines up with the 'A' which indicates advance. what should this setting be.no probs once its started but u have to swing & swing. plug gaps are hacksaw blade thickness.fueling not sure.checked plugs --slight brown in the middle & black outer. any ideas?
