Using the phone to connect...my return spring is mounted to the handle . There's probably about 2x the tension compared to the that W Winn detailed in his write up.
the original design connects the mold carrier to the rear of the frame, I believe.
I deviated just for the sake of it. Many times just the return spring if the cylinder is sufficient but there is some insurance with a heavier dpring
Anyway, the mold carrier arms were stuck in the full open position with the spring connected . It just happened on a cycle.
at night I took the mold arms off the main assembly and inspected them as well as the 2 partitions that flank them . The arms had some scratches but there wasn't an
obvious detent on anything
i added some light oil to both part, cycled manually a couple times, and it made a world of a diffrence. It retracted.
I didn't exaggerate. Once stuck, no lubrication, no return of the mold carrier--very strange
