The casing is still on the ie engine and the carbed one is completely apart so will be easy to compare the parts when I get into it.

I think what the issue maybe is the combination of ignition pickups / flywheel / crankshaft. The ie engine has the 3 yellow wires and the carbed version has 2 but its the pulse coils that are different as the ie motor has 3 wires where as the carbed version has 4

If the ie coils will power the Ignitech unit ok then that should be much easier or am I missing something really obvious here?
