Did anyone else have tight wheels? Mine barely spin on the 'axle'. (not I have the 30cc version) I cant pull the wheel off w/o breaking the pant. How are you guys replacing the wheels?? I'm considering dremeling off the 'axle' and putting a Dubro EZ Axle on...but that would also require me to dremel off a portion of the 2nd wire thats braised/soldered to the long one. Oy! Help please!
