Hi everyone,
Thank you all for the good advice and troubleshooting. I changed needle, thread, re-threaded, tried 2/3 holes on the one near the tension, turned the pigtails, and for a few minutes we were back in business. But I guess the old fella must have heard me on the phone trying to arrange a well-deserved spa date for him, because he started acting up again. I think I will step away and see if we can get a service scheduled soon.
Thanks for sharing your wisdom and experience - it’s so encouraging and appreciated.
Have a great weekend everyone,
—JD
