Anyone familiar with this type of MTH Passenger Car Truck? The coupler release sags and shorts out the track. Spring is not retracting it because it sticks. Worked it back and forth, but still not smoothly retracting from the spring like the other truck. Pretty new. Didn't want to disassemble it because it seems pretty flimsy. Retracting spring is under the lever behind the coupler. This type of lever is activated by pulling BACK on the lever instead of pushing it down.
Right now there is a piece if electrical tape over it which temporarily solves the problem.
Thanks,
John
