I started to have loops 4, 5, and 6 to each row. I picked them out and changed needles. I tightened the tension, no luck. I took it to a repairman and he said it needed a M hook because the outside edges of the M hook were sharp and that was causing it to loop. Is he feeding me a bunch of bull? I have not had any problem with machine other than it broke a needle on the quilt before this started to happen. Thanks.

While I'm not familiar with this brand machine I am familiar with sewing machines in general (and especially Singer antique-vintage-modern machines) and if your repair tech is saying you need an M hook, he's telling you the straight story.
Your threads are catching on the 'burred' bit on the hook, causing a 'stutter' in the machining that in turn causes the loops.
Have him change that hook ASAP so you can get back to quilting. Also, would you update to let us know what it cost you to have it changed so that we'll have the info for future reference?
Also, give this pdf a read - you may want to ask your repair tech what caused the hook to burr so that it doesn't happen again any time soon:
