Yes, this would be my suggestion. When Dave has been here, I can't tell you how much better my machine moves. I have an Older Millie with M & M wheels. I have no problem moving my machine overall, so I am always so surprised how much lighter it feels when Dave fine tunes it. Also, have you cleaned your wheels? If I feel like it is a little sluggish, I clean my wheels by running them over several layers of cotton batting. You won't believe the junk that comes off! I also clean my rails at the same time. These are great machines. You will find the solution from the people here or the company.
