I am very discouraged with my HQ Sixteen. Tension is always a problem. Even use the TOWA and check tension with every bobbin. It looks good to start with. The top tension looks great but sections on back will be a flat line and could be pulled out easy. Had someone tell me I am just too particular! Anyway right now my regulator is giving me fits. If I go up and down it works fine but from left to right it is sluggish and won't stitch with a darn. Have checked all my connections, etc. Everything looks okay. Any ideas? Do the cables wear out? I am at my wits end. My nearest dealer is 3 hours away. Would appreciate any help or advice.
