Binding flywheel motors

My flywheel is having problems. At first I tried a 7:1 gears ratio on my flywheel and that didn’t run because it was on a green motor. but I have tried a 1:35 (7:1 and then 5:1) and that didn’t run. Then I tried a 1:25 and that bound as well. basically what it did with both is that it spun the wheel not even a quarter rotation and then it stopped spinning. the gears axels also move a little bit to the direction that the motor is spinning so I think it might be binding but I don’t know how to fix it.
Edit: I can turn the bottom gear with the wheel but I can’t turn the top wheel because the first metal gear doesn’t turn

does it spin well by hand? how many motors are you using? are the spinning the correct directions? a picture would help a lot.

It looks like the spacer here is contacting your gear, that could be the issue? I know that with 12 tooth gears I’ve had to use the smaller .375in OD spacers instead to have it mesh better with other gears.

And the gear teeth look damaged.
