I meant to post a query here, instead of on my “Current Projects” thread,
regarding the subject motor, but here’s the link to the dilemma on
the last post.
Perhaps you’re “loosing it” and that extra line wasn’t really extra, but
rather fell out of place, and perhaps you couldn’t tell with the power

There also may blockage, like insect larve & mud etc., on the power head
discharge, you might find if you remove the power head. Good luck,
and we expect a test run video of the Hiawatha soon!
