Hi Dav,
Never use lighter fluid unless you don't want it to run again, You will have to strip the motor down an clean it with a fibreglass burnishing brush that you can get from your local model shop then clean the brushes an the copper contacts on the motor then re-assemble the motor an try it out. as for the tender wheels there may be a screw at 1 end or the other if not there may be some locating lugs on the sides at sole bar hight at the bottom of the body. Just place a flat screwdriver an gently slide it between the frame an the body an slide it to one end or the other, i hope this helps. Phill.
