When I turn to the left or right on my 73 atc 90 it seems like one of the rear wheels almost locks up. When driving it or pushing it and turning, the front wheel drags or gets pushed. Very wide turns are not a problem. I would estimate I am turning the handle bar approximately 30 degrees from straight ahead either way when the problem occurs. I got this machine for free. It runs well and drives. I have no idea what the PO did with or to it. He did replace the balloon tires with knobbies and split rims. Other than that, not sure what he did.
Any assistance would be appreciated.
Thanks.
