Base Tweaking Help

[warriorman]

Ok guys , I'm new at this and I may not be doing something right. I have been trying to tweak some miggles TTC bases and having problems with them. I read a couple post on here that said that a whole lot of guys was having same problem because of the quality of plastic they were made from. I also have tweaked a could of buzzballs bases and they have worked out. I may also have a problem as I am using an older board with a single motor. Any ideas ? Thanks for any/all help !
