I understand that this particular T34 is a pretty old model now from the comments earlier. Is it possible that the main gear legs have been bent back a little over the years and many dozens of landings? It may be as simple as re-forming the legs so the wheel axles sit a small amount forward of their present location. If this issue of not rotating well is fairly new on an older model that used to land and takeoff well then this may be the change that occurred.
What Jester said above or getting very close to what he said could be as simple as that small tweak of the main gear legs to move the wheels. Of course though if these are retractable gears and they work correctly then this is a non starter of an idea.
