On the E-start, how much did the guy who did the kick only remove of the starter system? Depending on just how much he removed, putting the starter back in may not be enough.
The starter turns a set of gears under a cover behind/below the drive chain front sprocket. These gears turn a gear on a cross shaft. This shaft turns gears behind the clutch that turn the bendix gears. These bendix gears engage the teeth on the crank.
Some just remove the starter, others remove more, some even go so far as to remove the shaft that the bendix gears mount on.
If the cross shaft and the gear on the starter side have been removed, you need to split the cases to replace.
