I've got an '04 Bombardier 150 with a sticky spark advance link. When coming off the throttle it likes to hang and not follow the throttle linkage back to it's home. Usually it'll stop just short of being fully released. Now traditionally on older models it sounded like the advance mechanism had brass rings that the linkage rode on underneath the stator. This model has the optical sensor.
When the spark advance link gets moved by the throttle link, and the optical sensor is rotated about the timing wheel, is that the only thing that advances timing? Or is there something else going on beneath, just like with the older models? I was originally under the impression I'd have to tear the flywheel and stator off to remedy the sticking link, but now I'm thinking I just have to lubricate the plastic collar support for the sensor. The red marks show where I'm talking about lubricating.
