yeah jacob I hate rechargable igniters. I recommend getting a igniter with alligator clips and a big fat 1.5V hobby battery. These seriously last for about 6 months!! I too was sick and tired of the igniter running out too quickly and it soons becomes a liability especially if you an running the engine in. It basically makes the task impossible to do.

Inregards to the factory settings, yes dont always take what the manual says as gospel. A good start point is LSN flush with throttle collar and the HSN should be about 3-3.5 turns from in.
