Just an update. After backing off the friction screw quite a bit I haven't boiled water since, I can't believe the previous owner didn't adjust it years ago. The lever is very smooth and still srays in place on its own. I didn't want to hold it for miles while underway...
We've been out in it a half dozen times. Now it's put away. But we really enjoy it and can't wait till spring...
Thanks for the help...
