BlackMax runs rough at 1-2K rpms-Why?

[Airslot]

Here's a thought. Check all your connections in the switchbox area making sure everything is clean ans tight. THe stator has three sets of windings, low spped, high speed, and charging. You might be losing the low speed winding in the stator. If you have a manual you can check without pulling the flywheel. IF you hava meter I could get the wires and readings for you if needed. If the low speed windings go totally you'll be dead in the water. I lost the high speed windings two years ago and it wouldn't run above 2k or so.
